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 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?
Try replacing the spark plug before doing anything else, is there gas in it?
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.
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 can't get my 125 John Deere riding lawn mower to fire up. It has plenty of gas and the battery is fully charged.
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 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 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.
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?
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.
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.
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 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.
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.
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 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.
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 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 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.
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.
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?
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.
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.
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 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?
My husband says sounds like the needle seat is stuck shut.
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?
By Mike L.
Change the celluloid and put a new battery in it. It should work great after that.
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 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
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
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.
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.
By Mike W from Albertville, AL
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 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 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.
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 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 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?
Check the fuses.
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
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 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.
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...
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?
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.
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.

By Jeff from Centerton, AR
Are you sure the air gap is set correctly?
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.
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 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.
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.
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)
My Toro riding lawn mower is a year old. When I started it this year it wouldn't start. When I did get it started, it died after 30 seconds. Now it won't start at all, it doesn't even crank.
Orlando from Bear, De
I have a lawn tractor with a basic starting problem. When I turn the key in the ignition I hear a click but the engine won't crank up.
I just replaced the fly wheel and the starter on my lawn tractor. I was able to start it briefly and then it cut out. I put a new spark plug in it and a new battery with no luck. It still won't start.
I have an MTD Yard Machine riding mower with a Briggs and Stratton engine model # 42A707. It will not crank at all.
I have a fairly new Yard Machine riding mower that I'm selling. I haven't used it since September. It's been covered with a tarp against the snow.
My John Deere riding mower will not start. Could it be the safety switch?
I have a John Deere LA125 that won't start. The engine turns over, but just won't start. I replaced the spark plug, but it's not getting a spark. It simply quit while I was mowing.
I have a 1999 16.5 hp Craftsman riding lawn mower engine that I put on a 2002 18 hp Craftsman frame. After I put the engine on the new frame the engine won't turn over.
I have a 2002 Craftsman rider. It would barely turn over so I charged the battery overnight.
