Here are questions related to Riding Lawn Mower Won't Start.
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.
My Bolens riding lawn mower was working great til I hit a low spot with longer grass. It got really loud then shut off. When I tried to start it, it will start turning over then pop really loudly a couple times then smoke. What happened?
How do you access the solenoid to replace it? It is under the seat and I can undo the 2 mounting bolts, but can't remove it.

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.
Lawnmower want turnover replaced the battery, still want turnover.
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!

I have a John Deere 185 it cranks from the key. I have replaced the starter, the starter solenoid, the key switch, and sometimes it starts and sometimes it acts as if the battery is dead and then I reconnect and start.
I have a 21hp mower that won't start. I found fuel in the oil; is this a blown head gasket? It is a Briggs and Stratton.
By Lance from New Iberia, LA
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.
I have a Bolens mower. When starting, the flywheel turns rapidly, but the mower won't crank. Help please.
My Poulan mower 15.5hp will not start. I installed a new battery and a new starter, but it still will not start. Start spins, but will not engage to turn the motor.
By dromo55 from Harlingen, TX
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 have a Rally Roper 11hp ride on mower. The battery is fully charged, but nothing happens when you turn the key. Can someone help?
Ok (sorry for my English) I have got a Huskavarna 2148. The engine won't turn easily and when I take the spark plugs off it turns easily.
My Bolens tractor won't start. I need to push some snow. It turns over, but won't start up. Last time I had to hit the starter to get it to fire up. Any suggestions?
By Ethan R.
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?
Can the ENM hour meter box have anything to do with the tractor not starting? It makes a random clicking sound, but does not turn dials.
I turn the key and it makes no sound. The motor has spark; I felt it shock me and the battery is good.
My John Deere 300A won't start. I just put a new battery in it. It won't even turn over. There are no lights and no starting sound.
The new battery turns over good, but there is no spark. Where is the location of the safety switch that will kill the spark?
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.

Your engine has too much compression built up You need to check the intake and exhaust valve clearances
My Cub Cadet, single cylinder B&S will turn over when the plug is pulled, but dead heads when plug is installed. Any ideas?
My uncle disengaged my mower and now it won't start or turn on.
I got it into neutral, with the clutch engaged. When I try to turn the key nothing. It looks like the key is turning, but maybe the key is just turning itself not what it is supposed to?
My mower has no spark at the plug. I have replaced the coil and the plug.
How do you clean out the diesel in a key start lawnmower?
I have recently bought a new battery and ignition switch which has worked in the past. However, when I turn the key there isn't even the smallest sound. I have tested the battery and it is showing full power. The lawnmower is as dead as a nail. Suggestions?
I replaced the starter solenoid and still get the clicking sound. The volt meter shows low voltage on the low voltage side. Anyone know the cause of this?
I have a 1989 Cub Cadet riding lawnmower. I just replaced the condenser and coil and it burned out after 10 minutes. What would cause this?
By Nathan S. from Bark River, MI
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.
My Yardman 17.5 Briggs and Stratton will turn over, but won't start. I changed the spark plug and it still won't. What can it be?
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!
My Yard Machine with two cylinder Briggs and Stratton turns over really fast, but won't start. What do I check?
By Roger from Gold Bar, WA
I have a Murray with a 17hp Briggs twin. It won't start. It has a good battery, good blue spark, and cranks fine, but doesn't want to turn over. I cleaned the carb, poured gas and starting fluid into the carb and still it doesn't try to start. Maybe bad plugs?
I have a Murry 17hp riding mower. I was cutting the grass, hit a stick and it stuck between the mower deck and blade. The engine stopped abruptly. Now it will not start. It is getting gas, turns over freely, but there is no fire on plugs.
I have a 1975 John Deere riding mower, 200 series, it is getting gas on the muffler and won't start. It has spark.
My mower won't start. It smoked when it started and now it won't start at all. Where is the 12 volt fuse hidden? Where do we look? We can see 3 fuses, but they say the 12 volt is hidden. It hasn't started the last couple times, now it just clicks and does not turn over.
I took the whole deck off for scrap metal money. Now I go to start the mower and it won't crank. I tried to charge the battery and nothing. Any ideas?
My Toro Wheelhorse 14.5 mower ran OK then just quit. The battery and starter are OK.

By James E
I have a Huskee garden tractor 18 horse 46 cut. It will start and run fine, but once I shut it off it will not start. It turns over fine. I have to let it set a very long time to get it started again.
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.
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?
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 v13.5 hp Craftman riding lawn mower. With this mower it will start and idle, but when you raise the throttle to high speed the motor starts popping.
By Carey from Oklahoma City, OK
My mower has new solenoid, new ignition switch, and a new spark plug. I cleaned the carb, battery and charged it. The motor spins, but won't start what do I do?
By Steve T.
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?
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.
I have a 14.5 horsepower Briggs it cranks, but won't start unless I prime the carb. I replaced the air filter and fuel filter. I took off the carb and cleaned with carb cleaner and blew out all ports and put carb back on with no change.
By Ben B
The tank is full, it has a new filter and new fuel pump. What could cause fuel not to flow between tank and filter?
I have a commercial Cub Cadet recon Zero Turn and it won't start. When I turn the ignition it won't click, a few days ago it ran just fine then all of a sudden it won't even click. I've checked the plugs and battery and they are OK. Please give me some guidance.
By B. McMullen
I have a Briggs and Stratton 19hp mower, but the spark plugs have no spark I think. It turns over just fine, but it won't fully start. There is an orange wire but idk what it connects to.
I have a White riding mower. The PTO warning indicator lights up and the mower won't start. Any suggestions?
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
Riding lawn mower won't start up. I changed the battery and spark plugs.
Could be loose wire or bad wiring, bad starter or clogged fuel line. Does this mean, it will not turn over or what?
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?
By Bekah G.
After my mower sits for a couple days it takes a lot of cracking for to start.
I have a 14.5 hp Craftsman riding mower with a Briggs engine. I bought a new battery, it started fine for a few weeks. Now I need to jump it every week to start.
By John G. M.
I have a MTD Yardman Yardbug riding lawn mower. It's a 8.5 hp engine, model: 13b-325-401, year: 2000. It will not start, I turn the key and it sounds like its trying to start, but the belts underneath the engine won't move. They try to slightly, but then stop and nothing happens. And no sound at all. What could be the problem? Thanks!
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?
By Rick H
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.
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.
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?
By Antonio G
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?
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.
Try spraying WD-40 in the carburetor. It worked for me. Hope this helps.
My Poulan Pro mower will not turn over, nothing. I replaced the battery; fuse is good. How do I test the starter?
Try spraying WD-40 in the carburetor. It worked for me. Hope this helps.
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.
By Ricky D
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.
By Beechy B.

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.
By Ed K. from Riverside, CA
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 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?
By Donna E. Frye05/03/2013
Check the fuses.
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
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?
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 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?
Why does the engine turn over, but won't start?
By Kenneth B
My riding lawnmower keeps throwing fuses. What can cause this?
By Leon T. from Florence, AL
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.
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
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 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.
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
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
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.
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.
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 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?
By Dave M. from Nashville, TN
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.
By ED T.
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.
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!
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 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.
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 YTH 1842 Husqvarna. When I go to engage the mower every once in awhile it doesn't turn on.
Maybe you need a new battery.
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 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?

Change the celluloid and put a new battery in it. It should work great after that.
When I turn over it just clicks loudly or nothing. It tries to turn over.

By Joe Burto04/28/2012
Sounds like your battery is dead. May need a new one.
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.
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.
What should I do if my riding lawn mow want start?
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 Terry F
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.
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?
By Danny C.
My John Deere LA140 ride on keeps blowing a 20amp fuse when turning the ignition on.
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.

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?
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.
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?
By Singh from Victoria, Australia
Why won't my tractor start? What is the spark plug gap for a John Deere L130?
By KCR from Pineville, KY
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?
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 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.
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?
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.
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.
By Carla from Winnabow, NC
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 John Deere that will not start. I purchased a new battery and it still will not start. It will start if I put jumper cables on it.
By Carol from Rapids, MI
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
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 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
Also it might not be earthing properly when you replaced the starter motor and battery.
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 replaced it with a good coil, still no spark. I tried magnets on the flywheel VG, coil gaps 0.005 to 0.010" between coil "horns" and flywheel. I disconnected the coil earth lead to the switch and there was no spark. Any ideas please.

I had the same problem this spring. Check to make sure the brake engaged, the key is in start position and throttle is set to choke. If this does not work, be sure the air filter is clean - you can wash it but be sure it is completely dry. If it still does not start, check the relay module. I opened mine, be careful when you pry the module apart, cleaned the dust off the contacts, replaced the two parts and the engine started after several pulls. It is also a good idea to drain the gas out of the tank after your last mowing of the year. I always drain my tank and change the oil before putting the mower to bed. Hope this helps.
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?
My L110 John Deere mower has no spark at the plug wire. What could be the problem?
By Tom from Marblefalls, TX
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
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 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.
By drumn4state from Peoria, IL
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.

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.
bigzipper6 from Cuba City, WI
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)
