More often than not all you need is a valve adjustment. Its fairly easy to do. Just Google "Briggs and Stratton valve adjustment" and watch a video.

You'll probably find that the small wire to the bottom of the coil is grounded out and killing the spark. It could be pinched somewhere. Behind the starter is a common place. Or, the ignition switch...

I have a Briggs 22hp ELS725 v-twin engine on a Craftsman GT5000. I bought it at an auction. So I know nothing about its history. It will only run on the right cylinder. If I pull the left plug wire I...

When you say "trying to start" I assume that the engine is not starting. The rotation of the engine after it starts is what turns that gear on the starter and makes it go back down.

The good thing is that transaxle was very popular in Murray and Craftsman mowers. You should be able to find a good used one fairly cheap.

If you can push the mower and both wheels spin freely but the pulley on top of the transaxle will not turn then you need a transaxle. Most repair shops will not repair transaxles.

I just re read your post and Ballenger is right. If the pulley on the transaxle is not turning then there is a problem with the tension on the belt. There should be a pulley with a spring attached...

Is it hydrostatic or 5-6 speed?

Have you recently had one of the rear wheels off of the mower?

That usually means the seat safety switch isn't working.

It's a 2001. The seventh digit should be an 0 not a o.

Have you checked the fuse?

I have a friend that is working on a Sears LT/8 tractor model 917.25700. He inherited it with part of the drive linkage disassembled. He wants to put it back together and use it. He is trying to find...

It could be the fuse. You can follow the positive battery cable. It will take you to the solenoid. The fuse will be near it. Try pulling back on the deck handle while you try to start. The deck...

More than likely you have blown the fuse. Follow the red/positive cable from the battery. It will go to the solenoid. The fuse will be within a few inches of the solenoid.

Sounds like your carburetor needs to be cleaned or replaced. A stuck needle valve in the carburetor will let the gas flow into the engine when it is not running and fill the crankcase will gas.

Most likely you need to adjust the valves. There are some good videos on YouTube for "briggs single cylinder valve adjustment" I like the one from smalleng.com.

Its also possible that the carburetor has let gas leak through and into the crankcase. Check to see if the oil is overfull and smells like gas. If it is then you may just need an oil change and a...

Make sure that the fuse isn't blown. It is located by the solenoid.

These same symptoms occur when the carburetor sticks and let's gas into the oil. Is it overfull on the oil dipstick?

There is a slot in the wheel and a matching sot in the axle that the wheel slids onto. You should have a small square piece of metal that slides into those slots when the wheel is one that engages...

MTD's website doesn't recognize that model number. In most cases you can follow the red (+) battery cable to the solenoid. The fuse is typically within 6" of that solenoid. It is an inline fuse that...

Is this a hydro or a 6-7 speed?

You need to figure out whether the problem is gas or spark. Try pulling the spark plug to see if it is clean and dry. If it is put it back in and try spraying some carburetor cleaner into the carb...

First of all is the mower a manual or hydro?

If it's a hydro there should be a release arm that releases the pressure in the transaxle to make it easier to push the mower if it quits or runs out...

Looks like that was made by Murray.

The deck belt is a 037X93MA
The drive belt is a 037X97MA

Yes, the brake pedal has to be down for it to turn over. The deck must be all the way up too. You could have a blown fuse. It should be located by the solenoid. Just follow the positive cable from...

Remove the plate on the rear of the mower. There should ne two bolts on each side. Once that is off toucan have someone watch while you try to engage it and see if pulley and fan are moving. If they...

The first thing I would try is to take the gas cap off and see if that makes any difference. If the vent hole is clogged it will make it act like it is running out of gas because it can't circulate...

This is usually a symptom of a bad or disconnected seat safety switch.

I would verify that the belt routing is correct. Next, can you push the mower when it is in nuetral? If not then the brake is stuck not letting the transaxle spin at all.

Typically if the switches make something happen then they are OK. What I mean is if you lower the deck and it shuts off then that switch is operating. Or if you push down the brake and it stops then...

You can run it without the anti backfire solenoid on the bottom of the carb. You just take a chance of shearing the flywheel keyway if it backfires.

The most common problem that you might have is a sheared keyway between the flywheel and the crankshaft. If you pull the nut off the top of the crank you can see the groove in the crank and a groove...

But the starting problem may be the suggested problem in the previous answer. Good luck.

It sounds like the seat safety switch to me. Maybe a wire going to it is making a bad connection or broken.

If it has the handle that engages the blades on the right fender then it does have a cable.

If it is the type that is controlled by a rod, there is an adjustment on the small rod that goes to the deck almost directly below the handle that engages the blades. It is about even with the bottom...

The first and easiest thing is to check the vent hole in the gas cap. If it is clogged it will cause these symptoms. If that doesn't do it the engine may be overheating. You will have to remove the...

It sounds like your seat safety switch is no working properly. Make sure it is plugged in. If it is the check to see if it working when someone sits on it

Most of the Craftsman have a deck engaging lever just to the right of the steering wheel.

To answer your question, yes the transmission can be repaired. But I would suspect that it might be a linkage problem. Put the shifting lever in reverse and then look underneath at the transaxle to...

Here is the video I usually recommend:

Hey topthumb,

Both the previous answers could cause the problem. And, it is probably one of them that is the issue.

1) If the carburetor is leaking gas through when the engine is shut off it...

If it backfired it could have sheared the aluminum keyway between the crankshaft and the flywheel. That will throw it out of time and make it not start. This is a common problem after a backfire...

DG is probably right. If the valves are out of adjustment it will have too much compression and keep the motor from turning over. More than likely this is the problem.

Have you removed the spark...

You probably need to replace the drive belts. This mower probably uses the two drive belts along with a variable speed pulley to determine the speeds. There is no transmission. Look above the deck to...

We are the original owner. It was bought for us and donated to us by a member. It was sealed in it's original package. So we would have been the first registration on the program. The exact facts are...

Thanks jarkar777! That worked great..
