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.

Try replacing the spark plug before doing anything else, is there gas in it?

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.

17 hp Murray Mower Won't Start

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 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.

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.

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 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 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.

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 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.

18 HP Briggs Mower Won' Start

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?

Mower Motor Won't Run

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.

Kohler Engine Mower Won't Start

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.

Toro LX500 Won't Start

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.

Mower Shuts Off When I Try to Use

John Deere 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?

Riding Mower Won't Start

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?

RE: Riding Mower Won't Start

It sounds like you might have broke the shaft since the blades aren't working but the motor is spinning.. (10/01/2004)

By HopeRomine

RE: Riding Mower Won't Start

If mower won't start, check your battery posts. I find them a bit cantankerous on these small batteries. Usually the neg. is at fault. Be sure the charge is up. If not don't charge at 10amps, but 2 amps. (03/01/2008)

Riding Mower Won't Start

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!

RE: Riding Mower Won't Start

Check wiring and continuity with a volt meter and make sure its grounded and isn't corroded. (04/04/2008)

By pebley

RE: Riding Mower Won't Start

Thanks for the suggestions!

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)

By grumpy54

RE: Riding Mower Won't Start

I'm having basically the same issue, in so far as the click but won't start. I have charged the battery. The terminals are clean. I would love to hear what fixed your problem. Frank (04/18/2008)

By wvnomad

RE: Riding Mower Won't Start

I'll let you know Frank. I broke down and hauled it to the local Husqvarna certified repair shop. At this point they are stumped. I replaced the switch, solenoid, bypassed the 3 safety switches, replaced the fuse so that was about the extent of my parts swapping. It will be interesting to see what it was. (04/19/2008)

Riding Mower Won't Start

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.

RE: Riding Mower Won't Start

Update on my Husqvarna LR125 rider that wouldn't start/stay running. The dealer finally found that the "electronic module" that provides spark to the plug would break down after about a minute of run time and then would not provide sufficient spark to keep the mower running or to restart it until it cooled off. Still waiting on the part. This was the part that Kohler listed as, "hardly ever goes bad so look for other problems". (04/28/2008)

By grumpy54

RE: Riding Mower Won't Start

On some mowers they have a shear pin on the bottom shaft that is designed to break to prevent damage to the main shaft check that, if its broken just replace. The lack of spark could be a number of things if it is electronic ignition then the main control box has probably died if its an older model it will be likely be the condenser as these do pack up due to moisture. There is always a possibility that the spark is tracking or shorting so just check all leads there also may be water in the petrol tank or carby as that will cause a motor to die but you would normally have spark.The lack of spark seems to be the main issue in this case. brentnz (04/29/2008)

Riding Mower Won't Start

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.

RE: Riding Mower Won't Start

My husband suggests it may be a weak battery or a weak starter. (05/05/2008)

By Lorelei

RE: Riding Mower Won't Start

Greg, it sounds like it has enough to almost turn it over when the plugs out because the compression is lowered meaning less resistance and when it's in then there is full compression. Sounds like something is too weak, I'd start with the battery making sure the terminals are clean and the battery has water and is charged. (05/06/2008)

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)

RE: Riding Mower Won't Start

I have a Husqvarna with a Kawasaki 15HP twin cam engine. It was only used for 1 summer. It won't start, it would just spin. So I replaced the spark plugs and checked the battery. All good. Then someone told me to spray starting fluid into the air cleaner. When I do that it fires right up and runs until that fluid is used up. After all of this I would have to think it is the carburetor. It was all gunked up, so I bought a new one. Threw that on today and it does the same thing. I checked the carburetor and it is getting fuel in there. So what can it possibly be? If it fires up with starting fluid then spark and engine is definitely good. And it is pumping fuel, so I doubt the fuel pump is bad. (07/21/2008)

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)

Toro Riding Lawn Mower Won't Start

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


RE: Toro Riding Lawn Mower Won't Start

When people put away their mowers for the year many do not drain the gas out of the tank and then run the engine until there is no gas left in the carburetor. The old gas will turn into gunk. This may have happened to your mower. The carburetor and gas lines have to be cleaned out. Some folks add a gas stabilizer to the gas in the fall when they put the mower away for the year. I don't, as I have had bad results, so I clean out the tank and carburetor as explained above. In the spring I add fresh gas and have the battery charged and I am ready to go. Have been doing it this way for years with no start up problems in the spring. If you don't want to do this yourself call a small engine guy to do it for you. (08/29/2008)
