Hi Guys,
I was mowing on my Jake with the kohler 16hp k series. In less than 5 mins it just shut off. I have checked for spark with the plug out and on block. i can see spark. I took the carb bowl off and had some crud in it so I cleaned it out. Fuel does fill it back up. Also fuel will run with bowl off. Checked all the fuses and replaced them. I sprayed some starting fluid in it and it backfired. Turns over fine, just wont fire. Just got this running a week ago and other than some governor issues and some muffler issues it ran ok. Today on leaf day this happens. Also does anybody know where i could get one of these mufflers? My 14 hp jake needs an engine rebuild as it likes the oil. I have robbed some parts off it for the 16 hp but both mufflers are bad. Thanks.

This maybe a mote question but since it leaks oil and some engine have a pressure switch (I don't know if the Kohler K series does or not) have you check your oil level? When you say it backfires when you shoot starter fluid does it really back fire with a bang or does it try to start and dies?

The Tractor Model #, Engine model # would help.

Just a quick thought. Try changing the coil with a known good one. The K301 in my cub would run about 15 minutes and would just shut off. After it cooled for a while it would start back up and do the same thing in another 10 minutes of operation. I had a sneaking suspicion it was the coil giving me the problem because oil or whatever they contain was leaking out.

thanks for the input! I just took the coil off my other one and still no fire. I choked it and it just backfires. It just cranks over and does not want to fire up. This one does not leak oil or burn it as far as I know. Its a jake 1650 around an '82. It has the kohler K serieis 16 HP.

That carb may be dirtier than you think.

What did you mean " as it likes the oil"? That means to me it either burns it or leaks it. May want to check the flywheel key to see if it is broken. Also check and clean the flywheel of rust and dirt.

As Bill just said, I would check the flywheel key. If your getting both fuel, and fire, I'd say your timing must be messed up. (sheared key) Of coarse thats assuming the engine is still mechanically sound.

This is interesting, maybe dirty points causing weak spark.
If there was crud in the bowl, did you replace the in the tank filter?
Maybe an electrical wiring problem? You say you checked the fuses and replaced them?
We're they blown?
Sorry, can't help with the mufflers, you may need to fit something new, and make it work.

By the way, Wdwildbill, he's talking two dif tractors here.
A 16 horse he's working on and a 14 horse parts tractor that "likes the oil"

Backfire from exhaust or carb? My guess would be condenser or valve seats if the flywheel key is good and points timing is good. Just throwing darts at the wall, how about water in the gas?

Hey;

As Kenny said, check out your points "real close". I had a similar problem with mine and even after cleaning them, ran ratty.
Replaced with new ones (too bad from mexico) and ran way better. Cekc the plug and replace it while you are at it. Makes a difference, worth the bother. Lastly, Seafoam is a wonderful thing I learned to use., If the carb just needs a touch up, it will work for ya.
Hope this helps.

My lgt 165 did something similar and it had a burnt exhaust valve, and there was a crumb of carbon keeping it from closing fully.
