I have a 14hp kohler in a wheel horse (see pictures). It has sat 7 years and i got it running agian. It runs good. But when i was mowing somthing strange happend twice. I would be mowing along and all the sudden it acted like i lost power back fired and died. It did this twice. It would start up and run fine after. I kept mowing for a while longer and it never did it agian. What was or is the problem?

Just my guess and where I'd check - if you didn't replace the fuel line or completely clean out the fuel system, there could be a chunk of fuel line or other debris floating around in the carb bowl.  Wait for the right moment and it gets sucked up to block the emulsion tube.  Let it sit and that little bugger makes its way back into the fuel only to be sucked up again and cause a similar problem.

Bob, I would check for a loose wire on the ignition switch and the coil/points connections. If that is all good, check the Carb. bowl for a little water in it. Also sitting that long, you might want to pull the head and see if you have an exhaust valve maybe sticking. Several of the Kohlers I have bought that had set for a good while, had exhaust valves stuck.


Good Luck and let me know what you find out.

I'd just add that the points can cause grief and while you are checking the wiring check the condition of the points and set the gap to .020.

 You might have some dirt in the carb. Did you clean it before you got it running?

After sitting that long a time, old carbon may be breaking loose, hanging up a valve, and possibly shorting out the spark plug tip.  Either could cause backfire.

Seafoam fixes everything!

I've had a few engines do that after sitting for a while.  I usually change the oil & filter (if it has one), pull the plug and either put a new one in or clean the old one, and then add a generous amount of seafoam to the tank and try to run it for a while each day (unless I hear something that doesn't sound right.  Usually it will to this 2 or 3 times then I never hear it again.

All of the above are possibilities along with a sticking valve. Usually if you experience an issue like this after an engine warms up thought it is an electrical issue. Sounds like a bad condenser. Adam
