Mowing the grass is one of the rites of summer, but now your mower won't start. There are many things that can cause a riding mower to refuse to fire up. This is a guide about troubleshooting a riding lawn mower that won't start.
Here are questions related to Riding Lawn Mower Won't Start.
My mower just clicks when you turn the switch on. It has a new battery and belts. It only stated for a few seconds and died. Now all it does is click when you try to crank it.
The fact that it just "clicks" when you try to turn it over may mean that the engine has seized up. Lack of oil mixed in the gas could lead to this. Also, you may want to try to replace the carburetor. Plenty of "How-to" sites on Utube and choose a reputable online business for mower parts and they should allow you to return carburetor if that is not the problem.
I had it tuned up two years ago and was told the engine and machine was in great shape. However, when I went to start it this season, it will not crank over or make a grunt/noise. The battery is fully charged and it has fresh gas. I jumped the two wires going directly to the starter and got no response. Is there something else I can do before having to replace the starter?
I have a Briggs and Station 14.5 42in and it won't start. It acted like it wanted to start, then just stop making any noise. I charged the battery and it has 1/4 tank of gas. Still nothing. Any ideas?

I had same problem for two years. had to buy new push mower. Sears came out the following year and found the ground wire attached to mower frame came loose. You can not start engine without a ground. I did the same as you but bought two new battery thinking that would work.
I have a Husqvarna 42" riding mower and the fly wheel keeps spinning; it won't start. Any suggestion? Please? Thank you.

Woodruff key is broken, or bottom of carburetor needs work.
My Huskee riding mower will turn over and it sounds like it's spinning really fast. I was mowing the lawn and it made a big pop and died. Now all it will do is spin really fast, but not fire up. Can you help me?
By tinman218 03/11/2015
Probably sheared the key between crankshaft and flywheel.
I have a John Deere LA125. I bought it new in 2009. After sitting unused in the garage for the winter (5 months) I couldn't get get it to run. The engine wouldn't turn. There was either a clicking sound when turning the key or no sound at all. I changed the spark plug - nothing. I boosted the battery and it ran. I was able to cut the lawn then turned it off. A few minutes later, I tried to start it and it wouldn't start again. I have to boost the battery each time. Any ideas?

I have a Yard Machine 17.5 hp. Briggs motor. It turns over slowly and won't start. It has a new battery, new spark plug, new fuel line, and filter. I checked for loose wires. I tried to jump it directly from the positive battery post to starter, but it still turns over slowly and won't fire.
By Don P. 05/24/2015
Needs valve adjustment for sure. Google search gap for your motor and how to on Youtube. Trust me that will fix the slow crank. Many people buy new batteries every year and don't really need them.
I have a Murry Select 17.5 HP 42 inch cut mower. I hit a stump and the mower stopped right away, my husband changed the blades yesterday, charged the battery last night and went to start it today and nothing. It doesn't even try to start.
The kill switch from what we understand had been disconnected by the person we got it from, but if you touch the two wires together it causes a short that will turn the mower off. Please help.
By silverwolf311420 06/10/2013
I'm having a very similar issue with my murray mower, but I don't know where the kill switch is even located at.
My mower ran without any issues one day while cutting the grass but while going to put it up it started to run very rough and wouldn't start after that, it even burned out starter wire so I rebuilt the starter, replaced the key switch and still nothing.
I have a 42 inch Poulan Pro riding mower that won't even turn over. The battery is fully charged and I hear a click, but then nothing happens. It seems like the electric starter might be bad, but I'm not sure. Any suggestions?

By Deanj 03/13/2012
Maybe a better explanation of my situation will help. I bought a brand new John Deere LA120. After a few uses it would not start or I would get a click sound or it would just turn over once or twice then nothing. I thought it was the battery or an open ground causing the problem.
A newer high amp battery may not change anything. I carefully checked out all the wiring. Nothing. I asked a dealer. He said it was the valves out of alignment. I thought he was crazy. I checked with a second dealer and he said the same thing. He said they could adjust the valves but I would be back next year with the same problem.
His suggestion was to rotate the air intake counter clockwise that sat on top of the engine until I felt resistance then it should start. I rotated the air intake as he suggested and could feel the resistance and hear the cylinders and valves moving. Then it started right up. So that is how I have to start the thing every time.
Sometimes I have to turn the air intake clockwise for it to start. The air cleaner is the screen disc that sits on top of the engine and rotates when the engine is running.
My L110 John Deere mower has no spark at the plug wire. What could be the problem?
By Tom from Marblefalls, TX
By Bill 05/01/2010
Ive been a small engine tech for about 20 years.
It sounds like you have a bad coil.
I have a Toro Wheel Horse riding mower. I started it and pulled the choke up all the way really fast and now it will not start at all. I have replaced the battery but when I tried to start it, it just smoked. Then I thought it was flooded so I took the spark plug out and put it back in and then it just did not make any noise. Now I am trying to find out what is wrong with it.
By Kyle from Williamstown, PA
By jim 06/08/2009
If it smoked when you turned the key on and now nothing at all you'll probably find a blown 12 system fuse hid somewhere where you cant see it. if it is a blown fuse you have a direct short on the 12 volt line somewhere. When you find your short your mower will probably be fine then. Hope I could help if you need help finding the short list what model mower it is and ill try to find schematics for it on line and maybe make a couple suggestions.
I changed the oil filter, added new oil, new carburator, new spark plug, new fuel filter, new battery, new air filter, and new gas, but it still will not start. The flywheel is turning over, the muffler puffs occasionally when I choke, but nothing happens. I am stumped. I poured a teaspoon of gas in the spark plug area to see if there was fuel constraint which resulted in a few coughs through the muffler. What do I do next? any suggestions? Thank you!

could be the switch under the seat is bad. it can tell if you get off the mower and shuts off the engine.you can bypass with a short piece of wire
My Murray 12/38 riding lawn mower won't crank over. It has a new battery and solenoid? Help?
By Cheryl  07/07/2015
Check the fuse under the seat for the safety switch(that makes the mower cut off if you get off the seat) I think mine was a blue fuse.
I have model#42514XBA. It has a new battery, but won't turn over and there is no clicking? What could be the problem?
By Cathy from Starke, FL
By Cheryl  03/16/2015
Check the fuse connection under the seat, it is for the seat safety switch. It may have became disconnected or blew the fuse.
My Poulan Pro mower will not turn over, nothing. I replaced the battery; fuse is good. How do I test the starter?
By Jason H. 01/02/2015
Try testing the solenoid heres a video on how to www.youtube.com/watch?v=MsvJMnpQBas
You might also have a faulty safety switch. Hope it helps.
I have a MTD rider, 42 inch. It won't restart when hot. I replaced the ignition switch, solenoid, and coil. At first it starts right up. If I finish cutting the lawn and shut it off, then it won't restart. I need to wait until it cools down; then it starts.

I had this problem with a 18.5 hp Poulan Pro for years and it was very annoying in that: We are in the southeast and we want our grass cut before the heat comes. We had a professional law repairman to replace all of the things you named and the Poulan started running real good for 20 minutes and then we had better have a pushmower or swingblade around. I read someone's post and the post said the carburetor components were causing this problem. I went to Ebay and bidded on a new briggs and stratton carburetor for $57.00, and now that cut off problem is gone.
I have an YTH 1842 Husqvarna. When I go to engage the mower every once in awhile it doesn't turn on.
I have a riding mower with a Kohler engine. My starter is good, there is a new coil. It's getting gas through both lines on the pump, but won't run unless we keep spraying gas in the carburetor. Any idea why the gas is not getting into the carburetor?
By Karen  08/01/2011
My husband says sounds like the needle seat is stuck shut.
I have a Columbia riding mover with a 12hp with I/C (industrial/commercial) engine; there is no spark. Do you have any ideas what the problem could be?
By Aaron S. T. 07/14/2013
Take the spark plug wire, pull it out of the sleeve, and press it to the frame. Turn the ignition. If it sparks, you have spark, your plug is bad. If not, your magnet isn't making contact.
We have 2004 Poulan Pro 18.5 hp, 42 inch cut. I got it out to start the mowing and it won't start. The starter will engage, but will not crank. When we put the jump cable to the starter it spins. Does anyone have any ideas what my problem may be? I would greatly appreciate it. I'm 67, live on my little SS check and unemployment with no work in sight. Thanks a bunch.

I have a Polan Pro Riding mower. It will not start-no noise or anything. I replaced the selenoid, fuse, battery, and key switch. Still nothing. Can you give me any other suggestions. I have no way to get it to a shop so I am trying to fix it on my own.
I have a Briggs and Stratton 12hp engine in my ride on mower that will not start. I have replaced the battery and starter, and have cleaned the carburetor. The engine turns over slowly as if the battery is low on charge (although I have charged it up) and there is a good spark at the plug. I have tried jump leads off the car, but it does not help. Any ideas?
By gd21 from Sunshine Coast, Qld
By poutokaipara 04/06/2011
Also it might not be earthing properly when you replaced the starter motor and battery.
I am trying to fix my MTD/Powercraft riding mower. It has an 18 HP I/C B+S motor, twin cylinder. 42a707 series. It has a hydrostatic transmission. The starter will not turn the motor to start it. I have put on a brand new starter and it still will not turn the motor. Even when I jump past all of the switches and solenoids and jumper straight from the pos (+) battery terminal to the starter, the starter still will not turn the engine.
The battery is fully charged and tested so I have ruled that out. My question is could it be that the transmission belts/blade belts are too tight? Should the transmission belts be disengaged when trying to start somehow? Right now the belts are very tight all the time and the engine is VERY hard to turn, even by hand. I know it is not a compression problem, I have taken the spark plugs out and the problem persists.
It is not an OHV engine so I am not inclined to believe that it is a valve problem. Should the clutch be disengaging the transmission belt? What exactly does the clutch do on these machines? This may be a very vague question, but I have been fooling with this tractor for a week now and I am at my wits end. If more info is needed, or questions arise please let me know. Help me if you can! Thanks.

Well on my riding mower it has safety devices. One of which is the mower will not turn over unless I am sitting in the seat. If the mower is running and I leave the seat the mower will shut down. It is possible to over ride the safety device. If my battery is low I hook up my charger to the battery but I have to be in the seat for the mower to turn over. Once it starts I kick off the cables with my foot or have someone unhook the charger. I also use alligator clips instead of nuts and bolts to hook up the battery to the mower. makes it easier to disconnect the battery.
I have a Poulan PB195H42LT and I am unable to get it to turn over. There is no click or any other noise. The battery is fully charged and it was running good the previous day. I checked the user's manual and it suggested that it might be the fuse, but I have been unable to find it. The manual said that it was located in the seat with the safety switch, but we took the seat completely off and we could not find it. Is there any other place that we might look? Also, if the seat safety switch is unplugged, will the mower start?

I found the answer to one of my questions. The fuse is located beneath the solenoid, clipped onto the frame. There is a red wire going into it and one coming out of it. Fuse is good and it still will not turn over.
I have a 11.5 hp Murray riding mower, model number 387000x92a. The starter, carburetor, and fuel filter were recently replaced. I cut 90 recent of the yard when the mower went through high grass and cut off. When I tried to restart it makes a spinning sound, but will not start. It made the sound earlier when I ran out of gas, but I got it started. I have a Tecumseh engine. What is the problem with this riding lawnmower?
By Puertods 
By Myrna  08/08/2015
Did you check and clean the spark plug? Sometimes a little dirt/grass can prevent it from starting. That happened to my own one time. It started right up afterward.
It just keeps turning over and if you put fuel down the carb there are a couple of pops, but it still won't start up. It just keeps cranking over. I changed the spark plug and there is fire. The carb is clean.
By Sherri  07/19/2015
I would check the gas line filter and it wouldn't hurt to also clean the air filter.
I have spark, I can smell the fuel, it appears to have compression, but still won't start. There is a new battery, it turns over with good power, but won't start. What else should I check?
By LLeak 
I have a John Deere 135 automatic. The solenoid clicks, but it won't start. The battery is good.
By mitch.overton47 12/07/2014
Your solenoid went out. Get a screw driver and cross the two ends of the solenoid, it will spark but your mower will turn over. Or your battery is dead or close to being dead.
My mower has always drained the battery dead. I've replaced several times. Now I just put the charger on it prior to mowing. My problem is now, as soon as I connect the battery charger, the starter starts turning. I don't even have the key on. What is the problem here?
By Mark A. from St. Johns, MI
By Rob Powell 10/26/2014
Your solenoid is stuck open. Bang it with a hammer or wrench or replace it. Easy fix but kind of hard to get too but look for a inspection cover and remove it to gain access to it. Best of luck.
It was working fine. I transferred it from my daughter's house in Louisiana to Texas, knowing battery needed to be replaced. I tried to crank it when reaching Texas and it would not start. I purchased a new battery (good) and it still would not crank. It will not even turn over. Where would a shortage be from battery to starter? Please help, grandmother in Texas certainly needs a little help.
By Jason H. 01/02/2015
Battery to the starter would probably be the solenoid check out this video on how to test it
If it's fine you might have a faulty safety switch.
I have a Toro wheel horse 8-25. I cut the grass and it was fine. I went to cut the grass again and it would not start. It has fuel and cranks great. Any ideas? Thanks.
By Joe W.
By jlee121995 05/20/2014
The problem could very well be the carb is plugged. You need to remove the carb, take the bowl off the bottom, and completely clean it with carb cleaner
My John Deere 400 won't start and doesn't make any noise or anything.
By Jason H. 01/02/2015
Test your solenoid
And check all safety switches
Take a look at this video for how to test the solenoid
My lawn tractor won't start without jump starting.
My Yard Machine riding mower won't start. I changed the coil 3 times, each time it was changed it runs a bit longer, eventually quits, cranks, but will not fire. I have talked to a couple mechanics and they have no idea!
By DL from Saskatchewan
By mechanik  05/06/2014
Hello there, I'm sorry to say I don't have a cure for you but I'm in the same boat. Originally when I first started to figure out why it didn't start it was a funny thing. I put an inline spark tester and crank it over and it seemed to have spark but when I just tried a new plug and laid it close to block or head and it had little to no spark.
So I took and replaced the coil which is also know as a ignition module or a magneto and after looking on u-tube for gap etc. It fired right up so I figured I fixed the problem.
Well the next week I decided to replace the drive belt and after completing that (which was no fun), I tried to start and after checking all the possibilities of something I possibly might have do it ended up to have the same symptoms and it points to the coil being bad again. So I'm going to write information down on paper this time so I know what readings I'm getting before, after with both the bad one and the new one.
In all my years of being an auto mechanic I worked on many small engines that have your basic coil/magneto that sits on side of most all of them and they all serve the same purpose. to create spark from magnetic rector wheels that when the flywheel turns around it meets the magneto and sparks the plug. It's fairly basic and generally easy to diagnose but like you it sounds like we have the same issue.
Right now I don't have an answer but I will find out and I'll let you know what I came up with. it's probably something to do with a power or ground issue. 7 out of ten times that ends up being the cause. Take care.
My Briggs and Stratton 18.5 hp will not start, it won't turn over; it just clicks. I just replaced the solenoid and the battery is charged.
By Christopher C. 05/03/2014
Check for a proper grounding. Next see if your getting power from your battery to your starter.
I have a Bolens mower. When starting, the flywheel turns rapidly, but the mower won't crank. Help please.
By lawntech1983 05/10/2014
You need a let for the flywheel that's why it turns and no crank most likely. Hope that helps you.
I have a Poulan Pro 18.5 hp rideon mower with a Briggs and Stratton engine. Petrol has leaked into the oil and the engine will not start.
What is the cause and how do I fix the problem?
By Shane W. 05/05/2014
This happen a lot with all type of mowers best thing to do is put a shut off valve on your gas line coming from the gas tank.
I tried starting my riding mower and it would not start. It sounded like the starter, so I replaced the starter. It started right up, but the next time I went out to mow the grass the mower would not start. I replaced the battery, now all I get is a clicking sound and then a buzzing sound, again sounding like the starter. So I replaced the new starter with another new starter (not rebuilt) again it started right up. I again cut the grass, and the next morning being just curious I tried to start my mower and got nothing but clicking. Help. It is a Sear's 20hp Craftsman 42 inches.
By Jim H. from Foley, AL
By Small Engine Guy 04/12/2014
Your engine has too much compression built up. You need to check the intake and exhaust valve clearances.
I have a Toro riding mower with 16 HP B & S engine that sounded like it wanted to start but wouldn't. I thought maybe it was the battery, but the lights turned on. I tried to start again and it backfired. Now it won't even turn over. Any ideas?
By Chuck  07/08/2013
Remove the spark plug and check a carbon build up. If found clean the plug. Check and rest the plug gap as required. Check for the smell of gas in the combustion chamber. If there is a strong smell of gas, leave the plug out until the gas Oder goes away.
Riding lawn mower won't start up. I changed the battery and spark plugs.
By Carol  06/16/2013
Could be loose wire or bad wiring, bad starter or clogged fuel line. Does this mean, it will not turn over or what?
I have a Toro LX500 riding mower. My problem is that it won't start. When I turn the key, the top of the starter spins up and turns the flywheel just a little and then stops. Sometimes the top of the starter doesn't spin back down. It has a brand new, fully charged battery. I've had the starter off and if I jump the starter it spins just fine off the tractor. Do I need a new starter? I will gladly try any suggestion that someone has.
By patdennahower 08/25/2013
I have a Troy Bilt Pony 17.5 hp and it does the same thing. I took out the sparkplug and turned it over and discharged the gas from the cylinder. I got it too fire up and run but it did the same thing the next time I tried to start it. It floods and the compression is too high and won't let it turn over. I am trying to find out the reason why also. Any help would be appreciated.
When I try to start my mower the motor turns over about a full cycle and stops. It does this till my battery dies. I charged the battery and it does the same thing. Whats the deal here?
By Janette  05/27/2013
Try spraying WD-40 in the carburator/air cleaner. Hope this helps. It worked for me.
My Kohler engine 20 hp mower will not start. If you spray starting fluid into the filter, it will run for a few seconds and then it will not start. Can anyone help me? I believe it could be the carburetor. I am not sure because it is getting gas to the carburetor.
By Janette  05/27/2013
Try spraying WD-40 in the carburetor. It worked for me. Hope this helps.
When I try to start it makes a click sound one time. I know it's not the battery because without the clutch down no noise. I turn the key 50 times and finally it will start. Please help.
By Mike T. 07/12/2013
Sounds like your starter has a dead spot. Seems like you need to replace the starter. Sorry
I can't get my 125 John Deere riding lawn mower to fire up. It has plenty of gas and the battery is fully charged.
Take a look at the ground wire - the same thing happened to my Sears Craftsman mower - somehow, the ground wire broke and the mower wouldn't start or even turn over. My son reconnected the ground wire and it's been running OK since then.
Our John Deere 160 riding lawn mower won't turn over. We have a new battery, and my husband put in a new starter solenoid. When he turns on the key, it just clicks. He and his friend jumped it last week so we could mow, but that didn't even work this time. Any suggestions?
By Cindy R
By Deanj 09/09/2012
I have a JD 120 with the same problem. This how the JD told me to start the machine. The valves are out of alignment so on top of the engine is a round screen that spins and cools the engine when it is running. Turn the screen counterclockwise until you feel resistance then start it. When I do this most of the time the machine will start.
Other times I have to turn the screen several times until resistance and other time I turn it clockwise. Either way it is a pain.Dealer told me the JD people use a cheap Briggs and Stratton engine and sell these units to the big box stores to be competitive with the other brands. Dealer told me I should have bought the 3000 series JD mowers. He also said he could fix the valves but I would be back next year with the same problem. Hope this helps.
When I turn over it just clicks loudly or nothing. It tries to turn over.
By David E.
By Joe Burto  04/28/2012
Sounds like your battery is dead. May need a new one.
My Yardman riding mower with a 20 horse Briggs cranks, but will not start. It has good spark to both spark plugs. Comp. check good/values adjustment checked, and fuel shut off OK. I tried starting fluid and was wondering if the coil gaps could be wrong. I would like to know what air gaps should be on the coil packs. Or am I missing something else?
By Bobby F. 04/01/2013
Loosen both bolts that holds the coil. Put a business card between the coil and flywheel. Tighten the bolds and turn the flywheel by hand to remove the business card.
My Murray 17/42 Ultra riding lawn mower with a 17hp, ohv industrial Tecumseh engine needs gas poured directly into the carburetor for it to start. Once it fires up, it runs fine, but even after I let it run for a few minutes I have to take off the air filter and do it all over again.
Suggestions on what I need to do to fix it? I got it on trade and the guy said he was told it would cost like $40 to fix, if he took it to a shop, but there aren't any shops near here that I can take it too. I don't mind changing parts, but I have never had a Tecumseh engine before. I don't know where to even start.
By Bill L
By Will P. 08/18/2013
I have the same problem with my mower did you ever figure this out?
I replaced all necessary maintenance stuff on this mower, battery, filters, plugs, etc. and it still won't start. It cranks over ok but won't start. I fed fuel in carb and it will start and runs until fuel in carb runs out. Can anyone help me figure out why it won't start and run without feeding fuel into carb?
By Deanj 10/31/2011
Sounds like fuel starvation. There must be a fuel blockage some where between the gas tank and the carb. Could be anything from a kinked fuel line to blocked fuel line.
Why won't my tractor start? What is the spark plug gap for a John Deere L130?
By KCR from Pineville, KY
By Deanj 09/04/2011
I have a John Deere LA120 with the same issues. The engine is a Briggs and Stratton with 43 hours of use. I use a Champion RC12YC gapped at .030 inches. The first year the machine started great but not so now. My machine also will not start by cranking.
So, I bought a battery booster at my local auto store to add cranking power. I also bought a new battery with more cranking power but neither helped very much. I called John Deere but they don't have a tech service. They just refer you to your local dealer for service.
I visited one dealer who told me the valves are out of alignment. I thought that was a lot of BS. I visited another dealer who told me the same story. He said valves need to be aligned but within a year you will have the same problem. He also said the engine for the LA series is a piece of junk. Briggs and Stratton hasn't made a good engine in 10 years. The LA series is a cheap machine that John Deere sells to the big box stores.
He would not take my machine in on a trade for the John Deere X series which he said was a much better machine. He did give me this advise to start the machine. Lift the hood and turn the intake screen counter clockwise until you feel resistance. It should start. I tried it and I was able to start the machine.
The last time I used the mower it would not start turning the screen counter-clock wise, so I turn it clock wise and it started. The screen is the big circular screen with all the slots in it that sits on top of the engine. When the engine is running the screen is also turning at engine speed. Hope this helps.
I have a riding mower with a Kohler engine. My starter is good, there is a new coil, it's getting gas thru both lines on the pump, but won't run unless we keep spraying gas in the carburetor. Any idea why the gas is not getting into the carburetor?
By marsley_1029 04/13/2013
I had this issue a few weeks ago my toro wouldn't start unless you dumped gas in it. Take the carb off and clean it the floats are probably gummed up.
I have a riding mower that won't start. It acts like it wants to, but won't. I shot some starting fluid in it and it will start for a few seconds then dies again. Any suggestions?
By Deanj 04/26/2011
If the mower wants to start or starts with a shot of starting fluid, sounds like it is starved for gas. I would check out the gas line from the tank to the carb. May be a clog some where.
My Murray riding mower will not start even with new battery, plug, and blades. What else can I do?
By Chris from Gibsonville, NC
By marty  05/02/2011
Does it make any noise at all like it's trying to start?
I have riding lawn mower Ford R8 using Briggs and Stratton engine 8HP. After I replaced the gas line, I am having problems trying to start the engine. Anyone have an idea what should I do next? Thanks.
By js777 from Canton
By Deanj 06/18/2010
Well if the mower worked prior to replacing the gas line I suspect something wrong with the gas line. Could it be plugged, or have a kink in the line?
I would first see if gas is getting to the cylinder or in to the carb.
I think the gas is fed to the carb by gravity so there may be a air block in the line.
Iwould disconnect the gas line at the carb and see if gas is coming out the end of the line.
I have a Briggs and Stratton T1600 Twin engine on a riding mower. The mower is going okay. I replaced a newish coil with an older spare to see if it was working. There was no spark.
I have a 2002 Wheelhorse mower, model ch15s-44533, 315-8. I cannot get it to start. I replaced the ignition module (magnetic), spark plug, battery, and carb kit. It will turn over, but won't start. It was my dad's tractor and he's no longer here for me to ask. Please help.

Are you sure the air gap is set correctly?
I have an 18.5 H.P., Craftsman lawn tractor, model #917.275760. The problem is this: It will not crank up. The battery voltage shows 12.5 volts. I have changed the: ignition switch, interlock switch, seat safety switch, module reverse ROS (switch), starter solenoid, and starter. I have 12.5 volts to the starter solenoid, but no voltage to the starter side of the solenoid.
I have the four post type solenoid, two posts for the wiring coming from the battery (+) and two smaller spade connections. I don't remember which wire connects to which spade. The wires are color coded, one is coded orange and the other coded black. I know that one wire comes from the ignition switch and the other is the ground wire. I have reversed the two spade wires at the solenoid several times with the same results, the engine will not crank. (no voltage). All safety switches are making contact. Of course, jumping the starter solenoid, using a screw driver, will crank the engine. I'm at a loss, what more do I need to do?
There is a protection wire loop in the wiring circuit, I looked at this loop which is under the seat, near the seat safety switch. This is a covered insulated wire loop, color coded gray. This wire comes out and loops back into a small connector that is connected at the end of the wiring harness. I really don't know what happens if this wire loop is burnt out. I have no way to know this, since the wire is covered. I have looked at this loop, there is no burnt wire indication. Since this is a protective wire arrangement it should have a visual means to check it for a burn out condition. Why not use a regular fuse for this?
Can anyone give me more information, what to do next? This is really a simple electrical system, but it sure has me stumped. There is something else you ought to know, when everything was operating correctly, the engine was cranking alright, I installed a new mower drive belt. The belt was much too tight, when I tried to start the engine, it whined, but it has not cranked since. I thought I changed everthing that might have burned out, making the engine not crank. What say you? Let me know if you have an answer to this riddle. Thank you.
I have a 2186 Cub Cadet lawn tractor. It will not start. It has a new battery and iginition switch.
Everything is working except the air that would come out of the engine is not coming out. Why is that?
I put in a new solenoid and checked the starter, but it still won't start. When I touched the two screws on the solenoid with a screwdriver it started up. I was told if this was the case the solenoid is bad, but I just replaced it. Thoughts? Thanks.
I have a John Deere x300 lawn tractor with a Kawasaki 2 cyl engine. It will only start by disconnecting one or both coil ground wires. What part is defective?

I am helping someone with their riding mower, it is a 80s model Montgomery Ward. I just installed a new ignition switch since the other was broken. It does not turn over or make any sound when I turn the key. I bypassed the ignition and started it from the solenoid with a screw driver and it started up fine, but it runs like crud and barely stays on. It has good power and battery and the terminals are clean and new. What could the problem be? spark plug? starter?
This pertains to a 2006 Poulan 300 riding tractor 19.5 eng 42 in cut. The gas is all backed up in the carborater and the pipe next to the air fiter area. The mower, just this last start, was hard to start, but it finally started. It would drive 10 ft. or so then stall. Any answers on why this happened, this mower always started the first turn? And best of all how do I fix the problem, all help would be great. TKS

I have a 3 year old Craftsman 42" riding mower with a 420CC engine. I was 30 minutes into my lawn and it just bogged down as if it ran out of gas. There's plenty of gas in the tank. I changed my oil and filter earlier this season, but not the fuel filter. When I try to restart the engine, it just spins and spins and then back fires, but does not start. Could it be the fuel filter or something else? Any feedback would be appreciated.
I have a 10 year old Snapper riding mower with the motor in the back. For a while as I was mowing, it would just quit on me. Today I went out to mow, and it won't even fire! What could be going on? I did go get a new coil and put on it, and it still will not fire.
I have a Gravely MiniZT 1534 mower. It's about 8 years old and has worked well until yesterday. I went to start it and it acted like the brake wasn't on (ie., nothing happened when I turned the key). The brake was on, so I pushed the brake lever off then pulled it on again and turned the key and it started fine. It worked for about an hour until all of a sudden the blades turned off while in motion. I stopped and turned off the mower to check for a snapped belt or broken pulley, but everything looked fine so I went to turn the mower back on and nothing happened. I tried the brake (off then back on), but no effect. As I listened closely, I could hear one of the two relays whistle-humming while the key was in any position except off. Normally, a noisy relay equals a bad relay, but I bought a new one today and the mower is doing the same thing. The mower had two relays, both the same, so I even swapped the new one into the other position to check, but no effect, just the one relay is humming when the key is in any position except off.

I have an old Dynamark lawn mower that I decided to fix up this summer and I am stuck. It didn't start and only clicked once when I turned the key, so it didn't turn over. I replaced the battery, put in gas and oil (drained both before adding new) and it started right up. After idling for a while, I put it into gear and drove for about 10 feet and it died. It didn't really slowly die it was a quick cut off. A small amount of smoke came out near the air filter and in the oil container. I haven't got it to start since then. I took off the engine cover and found dirt/leaves on the engine and figured that's where the air filter smoke came from. I don't know why there was smoke in the oil container when I took out the dipstick. I replaced the spark plug and still no luck. What should I do? Also, I found a very small amount of oil in the bottom of the air filter holder after it died.

I have a Snapper SR 110 riding lawn mower with the 8hp engine and it was running fine the last time I used it a week ago. When I went to use it today I tried to start it manually because the battery was dead. It pulled fine the first 2 pulls, but on the 3rd pull it felt like compression was building up and then just seized all together. Does anyone know what may be causing this? It has not been run without oil or gotten hot at all. I charged the battery and all it does is click.
By adamsjh 
I have a Toro 15.5 HP riding lawn mower that will not start. I charged the battery until it was fully charged. It will turn over slowly, 2 or 3 times, but then it just clicks like there isn't enough power to turn it over anymore. The battery was new in March 2009, and the spark plug was new last fall. Can anyone tell me what is wrong? Do I just need to get a new battery? Any help would be appreciated.
I have a Poulan Pro 700 ex mower that will try to start and run for a few seconds if I pour starting fluid in carburetor. However it won't stay running. I have run carburetor cleaner thru and removed and changed the filter. I also drained the gas and added fresh gas, replaced in line fuel filter, and checked fuel lines. What is left? Please help, it's making me crazy.
I have a John Deere mower with a 19.5 Briggs that won't start. It is model 31P677. It is not getting any gas from carb. I replaced the carb gasket and needle valve, pulled apart and cleaned all ports, adjusted valves in 4 ex 6, and it still won't start. Any ideas?

My Rally riding lawn tractor isn't getting gas to the carburetor. What could be wrong?
I have a Murray riding lawn mower with a 12hp Tecumseh engine. The engine cranks just fine, I have spark after replacing the coil and plug, I also have fuel after cleaning the carb and the tank and cleaning the fuel filter. My only thought after that is compression, but there is a good amount of air coming out of the muffler when the exhaust stroke comes around. But it just wont start, is there any way to time those engines or anything or what am I missing?
I have a Poulan tractor. It is not starting up from the key, but is starting up when I try it directly from starter after removing the kill wire. But when I again put the kill wire on its place it turns off. Everything else is OK. So is it the solenoid or the clutch switch? Please help me.
I changed the deck belt on my Bolens yard tractor and now the mower will not crank. Sometimes I get a clicking sound and others I get the growl as the motor tries to spin. It doesn't seem to get enough speed to turn completely over. I took the belt off, charged the battery fully and it cranked. I replaced the belt and it does the same thing, clicks or growls as the motor tries to turn over, but it never fully starts.
I tested the old fuel pump on my Toro Wheelhorse 314 garden tractor by disconnecting the line from the fuel pump to the carburetor. No fuel was coming out. I thought the fuel pump isn't pumping fuel; it must be bad. I replaced it with a new fuel pump, but now I have the same issue. No fuel is being pumped. I checked and replaced the fuel line from the gas tank and gas is pouring out to the fuel pump.
What is up? Need help!
By Barry T
I have a John Deere 212 Kohler 12hp mower. I put a new switch, coil, points, and plugs and it still won't start. What can be the problem?
It has a good battery, new solenoid, and starter switch. It will crank when I jump the solenoid, but there is no current to gauges and spark plug.
The mower will turn over, but will not fire.
We bought a 2005 Craftsman riding mower used. We were told it was just brought back from the Sears repair shop with a new carburetor. For a second it ran and then we would put the blades down at full throttle and it would die. We disabled the seat sensor and it would start, but not at full throttle. We looked at the carb to find out it was never changed. We cleaned it and still the same issue. We bought a new one and installed it and now it will not even run. Any clue what we are doing wrong?
By Jen G
My Pony riding mower with a Briggs and Stratton engine worked fine two summers in a row, even after sitting in the garage during the winter. Last night I went to start it up, pushed it out of the garage, and turned the key, nothing. It doesn't even make a sound. Makes me think it's a dead battery, but could it be a fuse thing? How do I test out the various options? I know nothing about engines.
By Nathan C
I charged the battery and the mower still won't start. The headlights burn and it was running great 5 days ago. When I finished mowing I washed the mower off as I do every time and it has never failed to start. The mower is 2 years old.
I have a riding mower with a 16hp Enduro engine. The carburetor is getting plenty of gas. It will only start when I pour gas in the carb. So I put on a new carburetor and I still have to pour gas into the carb to get it to run. Can anyone help please?

I have a L118 John Deere/22hp twin V OHV riding mower that just gives me grief every time I sit on the danged thing.

Any suggestions on what is going on?
By Robin V.
I have a Murray riding lawn mower. I changed the in line filter and it still won't start. I put some gas in the carburetor and it wants to crank, but shuts off. I need some advise please!
I have a Saber riding mower. Why is it not getting a spark?
I have a John Deere La105 lawn tractor. When I turn the key it makes clicking sound, but will not turn over. I charged the battery, replaced the solenoid, and replaced the safety switch on brake/clutch rod. Last season you had to push the clutch/brake in to just the right spot in order to get it to crank. That is why I replaced the switch on clutch/brake thinking that would solve problem. It still clicks when I turn the key, but nothing happens. I unplugged the switch under seat, but still to no avail. Any other switches that need to be replaced?
By Jae W.
I put the positive cable on negative terminal and put the negative on the positive by mistake. I reversed the cables and now they are on the right way. It will not start. What do I do next?
My Bolens MTD 13.5 Briggs and Stratton engine starts, but floods out after about 2 minutes. I take it off choke after starting, but it floods out. I replaced the fuel filter, hoses, battery, and spark plug, and it has fresh fuel as well. It ran OK a week prior so I'm not sure what happened. It is a 2 year old machine BTW. Do I need to clean the carb, or replace? Thanks.
By G Hunter
Will the starter still turn if your engine is seized?
I have a 2012 Troy Bilt 42" mower that cranks, but won't start. I did all the basics with fuel, plug, new battery, etc. Any suggestions?
I started the mower for the first time this year, it ran for about 2 minutes and stopped. I thought it was the gas, but when I tried to restart it there is nothing. I bought a new battery and still nothing. I have also checked the seat switch and it's working fine. Any help?
My 18 hp Briggs turns slowly and won't crank. It has a new battery, starter, and solenoid. It has low voltage on the cable at the starter when turning the key to start. However when the cable is unhooked from the starter and I'm turning the key the voltage is good. I bypassed the cable and went straight to starter from solenoid.

I was mowing with my Gravely 19 HP zt mower, and it just quit running. It still turns over, but the lights don't work and there is no spark.
I am using a snow blade on the front of my riding lawn mower. It will not start. I checked the battery with a multimeter. It's fine and registers 12 volts. I have 2 new spark plugs which I rechecked the gap and it looks good. There is plenty of gas. I apply the choke and immediately smell gas so I assume that gas is getting in OK.
My Craftsman riding lawn mower was running OK. I stopped and restarted it about 10 minutes later and it started misfiring and spraying oil and gas out of the muffler. It seems that now the gas flows straight into the crank case.
I have a Yard Machine riding mower. My husband was mowing the yard. When he was about half done the mower backfired and shut off. We haven't been able to crank it since. It only backfires. We don't know what the problem is. I need help please.

I was driving my Toro and I ran something over. It stopped immediately. I made sure that nothing was stuck and the blades were all clean. Now the mower won't start. It makes no sounds at all. I'm sure there are many things that could be wrong, but any ideas?
I have a Poulan Pro Hydrostatic riding mower. When you start the mower nothing happens, no sound, nothing. I replaced the battery this morning and still nothing, the ground wire is good. I can not find a fuse. The model # is PB195H42LT, serial# is 022112D003206.

I have a MTD 46" riding mower 18 hp, MD#SWC483021. All my mower does is click when trying to start it. I put a new solenoid on and replaced the starter. The battery is good and it still does the same thing.
If there is an inline fuse from ignition switch to starter on a Bolens 13.5 h.p. riding mower, where is it located?
Every time I turn the key to start my lawn tractor the inline ignition fuse pops instantly. Is it a relay or a bad ground? It is a 16.0 hp Sears lawntractor from 1992.
Where are the fuses in a Wheel Horse 244H?
I took my mower out of the garage yesterday, it wouldn't start because the battery was down so I had to boost it. I started the mower and put it on slow idle to let the battery charge. I went about my business while the battery was charging and all of a sudden I heard this loud exhaust noise like the muffler had fallen off the mower. I rushed to the mower and shut it off. I checked the exhaust and everything was fine. The problem is now it won't start and when I am trying to start it there sounds like there is an exhaust problem. This is a new mower I bought three years ago, 30 hrs on it.
By Terry C
My 21hp B&S Platinum Craft riding mower will not turn a full rotation. Battery (even jumped from truck), new starter--starter engages, but engine will not turn full rpm. It appears to stop in compression, when engine is at exhaust position (?); starter turns flywheel maybe 1 to 1 1/2 rpm, then stops. It appears too much resistance to turn flywheel. Possible cause? (Oh yea, mower, will not start).

I have a JD 18 HP. V twin; it's a Kawasaki engine. It has spark at the spark plugs and it's getting gas into the carb and to the spark plugs. It will crank over, but will not start and run. I drained the gas and put new gas in it and it still will not run, just will crank over. The battery and all are in great condition. What can I do next?Please I need help ASAP. I can't take it to the dealer cause of what they charge to fix stuff. It's a 2005 or 2006 model. Here are some of the numbers I took off it, FH580VBS04-R, FH580VA94857, and KAXS.686N40B. It has been sitting unused for about 4 or 5 years, but like I said I have changed everything and cleaned out everything also. It just won't run!

I was driving my mower to the lawn. It went bang, stopped, and now won't start.
My Poulan (18Hp Briggs) riding lawn mower won't start. I changed the oil and filter, however I did not fill up the oil to required amount, as mower was on a slight incline. I added 1/2 quart and it started very well. Put into gear and started to move mower to level ground.
Then the sound came! Like I dropped a tool into the engine. I stopped the mower and checked the dip stick. There was no oil level and white smoke. I forgot that filter was dry and that any oil put into engine would go directly to filter. There is no real resistance when I turn flywheel - after each revolution there's a clunking sound. What have I done :( Can I salvage it? What are my next steps?

I have a Yard Machine riding mower. It won't turn over by the switch, but I can jump start it at the starter with my jumper battery box. It started doing this about 3 weeks ago. I turned it off and when I went back to start it it would not turn on by the switch. After about the 8th time trying the switch it started, but hasn't since.The pto is on the right and you have to pull it all the way back. The fuse under the seat is good. Thanks for any help.
I have a Briggs and Stratton mower and it won't start. I tried hooking up jumper cables and turning the starter over that way, but the starter won't turn over. I tried taping it, also tried a new starter, still nothing. When I turn the key I can hear a clicking coming from a little black module under the plate below the seat where the pos cable connects and another red cable that runs to the starter, it also has a small orange wire. I replaced that too and the spare one does the same thing. The fuse is also fine. I'm lost; please help!

By Cecil J.
We have a new battery and it started up the first time and then we went to start it the next time. It did the same thing like before then we jump started it and it smokes. Then it would run good and now all it does it just click and won't start.
First I ran out of gas, then when I got more I couldn't get the engine to fire up. I felt I'd run the battery down so I sprayed a blast of starting spray in through the carburetor. Now the engine won't turn, when it tries the overload button kicks out. I tried turning the flywheel manually, too hard. I removed the spark plug hoping it would relieve, no go. Any suggestions before my house disappears behind my yard?
Kohler engine on my 15hp John Deere riding mower won't start. I have replaced the battery and have a new solenoid in it, but now all it does when I turn the key is make a slight whining noise. Any ideas on what it may be? Possible starter? Also, I have checked all connections. Thanks!
I have a YTD yard machine 14.5 Briggs and it will not turn over fast enough to start. Even jump starting it isn't working. I replaced brushes that had been replaced in the starter. Any idea or ideas how to fix the problem and get it up and running? I am ready to throw it over a cliff.

I have a Weedeater brand lawn mower with a 18.5hp Briggs and Stratton motor. I noticed the starter gear was stripped horribly so I replaced it. It isn't turning the gear for the starter. I also noticed a little wear on the shaft of the starter. Is it possible to put the gear on backwards or maybe is the shaft bad.
By Dharris from TN
The starter motor gear will not engage the flywheel when the key is turned to the start position. The gear hits the bottom of the flywheel. The motor cannot turn because the battery voltage has not been applied to the starter motor via the solenoid because the flywheel limits the solenoid travel. Releasing the key drops the starter motor gear back down and the gear turns counterclockwise a very small amount. The starter motor needs to be "bumped" as many as 15 times before the starter motor gear will mesh into the flywheel starting the engine.
By Jerry J
I replaced my battery and it started right up today. Had it going for a good hour or two, then I shut it off. After about 20 minutes, I went to go turn it back on. All I got was a clicking noise, so I tried jump starting it (which worked with the old battery), but nothing happened. I really would like to not buy another brand new battery, do what do I do to make it turn over and work?

PS. I just bought it from a friend and it was running fine for a few weeks and cutting the lawn. But I haven't used it in 2 or 3 weeks and now it is doing this and not turning on.
My ride on lawn mower starts fine for my guy friends, but not for me. It shuts down when they get off the seat so I'm wondering if I'm just too light (100lbs). If so what can I do? Besides gain weight!
I just replaced the battery. When I try to start it, it will not start. I have to hook the charger up to it and then it will start. Any solution?

I have a Craftsman Lawn Tracker model no. 917.28910. It is only about 4 years old. I have a problem starting it. I changed the battery and it will start on a dime. I will mow the lawn, clean it up, let is sit for a while, and try to start it up again to put it away and it won't start. It will click and sometimes if I hold the key to start a little longer than usual, it will turn over and start. Most of the time it won't do that either. Is there something that charges the battery while it is running such as an alternator? It seems after it starts and runs, the battery drains to a point that it won't have enough juice to start up. I changed the spark plug and no help there. Checked all the wiring and nothing is loose or corroded. Any help or ideas on what to do?

The engine is running fine. The male connection of fuel solenoid broke off. I replaced it with part Sears sent me. Now it will crank, but not turn over. It will run a few seconds if gas drops are put directly in carb; there is gas in bowl.
The gas is good and there is no fire at plugs. I replaced the coil. It fired 2 or 3 times, now no fire, no spark at wire. I disconnected the kill wire, no luck.
I had an outboard engine that had a flywheel magnet that went bad one time. It was weird, but it happened. Could this be the problem?
I have a twin cylinder 18.5 horsepower intek turbo cooled Briggs and Stratton engine on my Craftsman riding lawn mower. This is what happened and what I've done, I was finished mowing my lawn and tried to disengage the blades, but they didn't disengage, they just kept spinning, I noticed a spot I wanted to go over again so I started to drive in the direction without re-engaging the lever for the blades since they were already spinning with the lever down. All of the sudden I heard the engine not sounding right, it was a clanking noise so I shut the engine down right away. I checked the oil and it was a little less than a quart low, there was still oil on the dipstick. I tried starting it and it would not start.
This is what I've done, checked compression, a little low at 60 psi, but I read that it holds 70, also read that there is a compression release so you could have false readings. Either way there was compression. Checked for spark, changed plugs for the heck of it, gas was getting to the carb so the fuel pump is good, replaced the fuel filter, juiced the battery, adjusted the valves, added the oil it needed, drained and replaced the gas, went as far as spraying starter fluid in the intake and the cylinders! All of this and still it will not start. The engine turns and sounds fine, but will not fully start, not even a backfire, almost like I want to push on the pedal and give it some damn gas! The flywheel key is fine, I can hear my solenoid working, not sure if there are any safeties that still spin the flywheel, that's the only thing left that I could think of. Can anyone help me out? Thanks.

I have a Snapper key started mower. Every time I go to crank, it just clicks. When I turn the key the motor clicks then doesn't want to crank.
I have to use a charger to start the mower. It is a new battery. The mower voltage indicator does not move. Maybe a ground wire or alternator, or...? Please help.
After changing the battery out on my Husquvarna riding mower it won't start. I have checked battery connection and the only fuse can find. Even the hour meter won't come on.
I've got a Craftsman 14.5 HP electric start 42 in. 6 speed lawn tractor that won't turn over. I removed the deck and all PTO handles/levers when I parked it 8 years ago.
I want to get the mower up and running again and eventually start converting it to a racing mower, where should I begin? I've tried jumping it to no avail, I can't even get a clicking noise to come out of it.

I have a Yard Machine. I just recently replaced the blades and V-belt; though being I had the mower on its side for a bit, now the mower is not starting like it should. I found that oil got into the carb bowl as well as on the spark plug. Does anyone know what this could have done? When I did briefly get it started it smoked very badly. When I shut it off it would not start again.

Can anyone please tell me why a starter would spin backward? It won't start. I checked the battery, wire, and starter. There was a blown a fuse. I replaced it and noticed the starter is spinning backward.
I have a White riding lawnmower with a 20hp Briggs motor. I was getting it ready for grass cutting season. I charged the battery and it fired right up. So I loaded it on my trailer and brought it home, about a 20 minute drive. When I got home and went to start it, it didn't make a sound, I checked to make sure pto was off, I tried boosting it and still no sound. I removed battery and cleaned the posts and made sure everything was tight.
Thanks for any help you can provide.
I have a JD LT133. I have just replaced the battery in it. It will not crank or turn over unless I use a rocking motion to the entire mower. Once cranked it runs smooth and steady, but once shutting it off, it will not re-start or turn over. What can be the issue with this mower?
By Howard C
When you turn the key on this 18.0 hp B.S. it act like it wants to start, but then it just turns over.
I was on my 38/145 MTD Yardman rideon when it stalled. Tthen there was a loud bang and now I can't get it to start. Do you know what this could possibly be please?
I have a one year old mower that was working well, then shut off. I cleaned plug, changed gas, cleaned everything, and charged battery and it still won't start. It is getting gas and is getting spark. The model is 13AM772S000. I am pretty handy with some things and have all tools needed. Thanks.
Is the oil supposed to smell like gas? Anyway, it doesn't start. It seems like it's not getting gas. I changed the gas filter and added new gas. It turns over good and sometimes fires over, but won't start?
By Steve from Ashtabula, OH
I have a Husqvarna lth130 riding mower with a Kohler 13hp engine. It was running fine until yesterday, when I almost ran out of gas. I'm thinking the carb is clogged with gum and junk, but I am not too knowledgeable in this field. I also read about the low oil safety switch, where is that located? I have fresh gas, and gas is flowing all the way to the carb, but looking down into the air filter I don't see any gas in the bowl? Any suggestions on what I should do next? I would appreciate everyone's help! Thanks.
I replaced the battery and my mower still needs a jump after sitting for a week. It is a John Deere L100. What could this be?

My riding lawnmower keeps throwing fuses. What can cause this?

My Stanley 48ZS mower will only run when you hold the key in the start position. What's the problem?
My lawn mower won't start without the choke on.
My John Deere won't start. It has a new plug, neutral switch key switch, battery, solenoidal, and I cleaned all grounds. When I hook up the battery, I have got lights, but when I turn the key nothing happens. What do I have hooked up wrong?
The tractor was handed down to me from my wife's grandfather about 3 years ago. When I first got it it wouldn't start without a jump, but after I drove it a few times it would start on its own, usually for the rest of the summer. This year was the same until yesterday when it wouldn't start at all.
I figured the battery had finally had enough so I pulled it out to get a new one and found a mouse nest behind the battery around all the wires. I removed the nest expecting to find chewed wires, but did not. I put the battery back in and the tractor jump started right up, ran for about 20 minutes, shut off and would not restart, jumped or otherwise. So I replaced the battery today and still nothing and I mean nothing not even a click.
By Jim W.
I have a Poulan Pro riding mower with a 25 hp Briggs and Stratton engine. The mower itself hasn't given me one problem until this past summer while I was in the middle of mowing. While mowing the backyard, I could feel the mower dying on me and watched the battery meter slowly fall and then it shut off and I haven't been able to start it since.
I have replaced the battery, starting solenoid, ignition, and the only thing that happens is the lights come on and the fan will click when you turn the key. We also tried jumping it off of a car battery. Still, no start. Any ideas?
My riding mower needed a boost, but the connection was wrong on the mower battery negative to positive, positive to negative, but was connected correctly on car. Now my lawn mower won't make any noise at all, even with a new battery. What needs to be done to get it running again?
By Clayton D from London, Ont.
I have fire from the battery to key switch, but no fire from key switch to solenoid. I put in a new solenoid, and it still won't start. I can jump start it from solenoid and it turns over. Can any one help me out. Thanks.
By Bobby from Lake Arthur, LA
I have a Troy Bilt Pony 42 inch mower that won't start. I was operating the machine and it began to run out of gas. I inadvertently shoved the throttle into choke, the engine killed and then I refueled. This was 4 days ago and the mower still won't start with the throttle on slow run or choke. I emptied the bowl below the carb and tried again and it still won't start. Any suggestions?

My lawn mower keeps flooding out on me. It runs fine when I unplug the hose coming from the crankcase to the bottom of the carburetor plate that the fuel line connects to. What is wrong with my mower?
My Toro Wheel Horse riding mower was idling and just shut itself off. I tried to restart and it does not make any clicking noise from key turning or any kind of noise of motor trying to turn over, just silence. The battery is brand new.
I checked the throttle to see if it was moving OK and it appeared good. I tried to check any loose wires, spark plug connection, battery connection, removed any blocked lawn cuttings, and still not a bit of noise to start the rider. I was cutting the lawn for about an hour before this trouble began. It was serviced in March 2012 for the annual maintenance at a Toro dealer. Yes, there is gas and oil in the machine. Could it be a faulty starter or loose wire. What else can I do to get this working again other than calling the dealer? I live on a farm of over 4 acres of cutting. Help!
My Toro Briggs and Stratton riding mower will crank, but will not start. I changed fuel filter, spark plug, and battery. It ran on starter fluid for a few moments, but then just died.
We ran our recently tuned up LX175 John Deere rider out of gas now it won't start up. I changed the fuel filter, still no luck.
Does anyone have an idea how to fix?
My Poulan riding mower cranks, but won't start. It is a model #27147 with a 13.5 Briggs engine. It is an older mower that a neighbor gave me, but there is no manual.
My Sears 20hp riding mower won't crank. I replaced the starter and solenoid. Every time I try to start the 20 amp fuse keeps shorting out. What next? This all started after I replaced a leaking gas tank. It is very frustrating. There is no crank when I turn the key. When I cross starter the solenoid with a screw driver starter spins, but won't engage the flywheel. I have spent over $200.00 with no results.
I replaced the spark plug and it has gas in it, but won't start. It kind of coughs, but can't ignite the engine. What do I do?
I have a Craft riding lawn mower the won't stay running. It also has a lot of back fire through the carburetor; it is a 15 horse.
I have an riding mower and the battery is newer, but just recently had a full charge put to it. When I try to start my mower it is dead, no spark, no nothing. What do I look for to track down the problem?

My Troy-Bilt mower will not start; only the headlights come on. I mowed my front yard turned the mower of, then tried to restart. It acted like it was going to turn over and then just clicked. Now there is nothing but headights.

I have an old Montgomery Ward riding mower with a 14hp B&S that won't start. It has needed a new battery and I've been nursing the old one. It started after a dragging turnover and I let it idle while I trimmed the weeds. I shut it off while I push mowed the hard to get to places and came back to mow with it and it wouldn't start.
It was like the battery was almost dead. It would turn slowly until it hit the compression stroke then drag. I tried to jump it with the charger/starter and nothing. I went out and bought a brand new battery and same thing! It won't turn over fast enough. I pulled the spark plug and it looks good, and turned the engine without the plug and it spun really fast. Is this a starter going bad? I figure that once it meets resistance with the compression stroke, it just gives up. This mower is old, but just keeps going.

I have a Toro Wheel Horse 15-38 hxl riding mower and it won't start. I took it in to get serviced and was told it was needing a new battery. I got the battery and still nothing. It doesn't do anything, no noise, nothing. I turn the key switch and nothing, but if I bypass to the starter it turns on when I jump start it and it works just fine. If I turn it off and on again I get nothing; it only turns on when I jump it. Any suggestions?
By leo98935 from Mabton, WA
It won't start with the key, but if you short out the solenoid, it will start and run. If you turn the key off it won't do anything. It has a new battery, new key switch, and a new solenoid on it.
My John Deere mower won't start without a little gas poured into the carb. Any suggestions?
I have a Toro riding mower. The battery is OK. It had a loose connection which had interfered with getting power to the solenoid. I wriggled the wire a bit and the solenoid began clicking. After a few tries the starter engaged briefly (a second) and disengaged immediately.
Is the starter motor connected directly from the solenoid to the starter motor? Could the loose connection which stopped the solenoid operating cause the starter problem as well? Is the starter mounted on the outside of the engine and does it look like an auto generator but smaller? The gear from that "generator-looking" item is under a small cover and when I took a look the small gear was disengaged from the fly-wheel.
I have a Briggs engine, 18 hp, on a riding mower. The engine will turn over, but will not not start. It seems to turn easily and then hard as you are trying to start the engine. I was told that a compression valve is not releasing properly.
I have a Poulan riding mower. I got my volt meter; with mower off it reads 12.7 , with the mower running it reads 17.6 until it engages the blades, then it reads 14.2. What's wrong? How can i fix it? I can only start it by jumping it off my truck. Thanks.
What should I do if my riding lawn mow want start?
My mower won't start. The spark plug has weak fire with an orange spark and then sparks stop while engine tries to crank.
By John A.
I have a Poulan with an 18.5 briggs. It turns, but will not start. I replaced the battery, drained and cleaned fuel tank, replaced filter; I have spark. I alos disconected line at carb and do have fuel to carb. It will start for a second if fuel is poured in carb then dies. Is this a carb problem?

My John Deere LA140 ride on keeps blowing a 20amp fuse when turning the ignition on.
I have replaced the head gasket on the Briggs and Stratton engine, model #313777-0134-E1, on my riding mower. It is breaking the fly wheel key and does not start. When we move the engine it moves smoothly and is not hitting anything. The push-pull rods are not bent. The valve tappet setting is also correct to specifications. Can you please advise?

My riding mower's engine just spins. All of the belts are ok. I was using it when a loud pop happened. After that, when I tried to restart it, the motor just spun as if something in the engine broke. Any suggestions?
My Husqvarna lr125 riding mower won't start. The batteries good, all safety switches bypassed, and new solenoid. It clicks when ignition is turned (same as before new solenoid). It starts when jumped from battery direct to starter. Runs maybe a minute before stopping. Any suggestions? Thanks!
John from Johnson City, Tennessee
The battery is new and terminals are good and clean and continuity is good.
What puzzles me is that it will start (by by passing everything) but only run for about 1 minute before it dies. When it dies it is an "electrical" kind of death rather than a "starved for gas" death. It makes me think that something is heating up and then not working? (04/04/2008)
I have a John Deere STX 38 riding lawn mower that I can't get to start. It ran fine all last summer, but unfortunately, I left it outside in the winter. I changed the battery, spark plug and wire but nothing. The motor just spins. It doesn't look like I'm getting any spark in the plug wire at all. Someone said one of the cylinders might be stuck, but I'm not sure. Any help would be appreciated.

My riding lawnmower won't turn over. When I pull the spark plug it tries to turn over, when I put it back in, it won't. Verified spark with plug removed. Not sure where to go or what's wrong? It's a Briggs and Stratton 18hp engine.
Greg from RI
You mention something on thrifty fun about the ELECTRONIC MODULE. I seem to have that problem. Power craft by Briggs and Stratton will start and run but when I cut it off to dump the grass it will not restart until it cools down. So when you mention the problem on the forum it sounds like that is my problem.
I do not know where and how to get a quote on the electronic module for my riding mower. If you could help, please let me know. Thank you for any help you can provide. Meng (07/15/2008)
-Will start and run but when I cut it off to dump the grass it will not restart until it cools down.
Meng, your description of your fault describes mine exactly. My ride-on mower has a 13.5 hp B and S Invek engine. It has magnetron electronic ignition. Just 2 yrs old. So, what have you done and replaced to get your mower going again? Thanks in anticipation of your reply. Sammy (07/26/2008)
