Question
John,

Thanks for the first tip...  I tried the starter fluid and got only a few "pops" and the rest was just the cranking of the engine.  The part numbers I have for you are for a Kohler Command 17.5:
Serial No.  3401333933
Spec. No.  PS-27509
Model No.  CV 491S
Family 3KHXS .4902GB

Thanks again for your help!
James

I have a problem with my 17.5 hp Kohler engine on my John Deere L110 lawn tractor.  I engaged the blade and the engine wanted to die.  I disengaged the blade and tried driving and the engine was backfiring and losing power.  When I got it to the garage.  I could start it a couple of times, but the engine continued to backfire even more.  Eventually the engine did not start, but will backfire while cranking.  I've replaced the spark plug and changed the oil since then.  Other than that I'm at a loss.  I know you've had a similar case and mentioned to adjust the fly wheel key, however, I'm not sure where that is located.  Can you help?

Thanks!

James

 Hello James:

 Try using Starter Fluid to Start the Engine. If it Starts and Quits with the Starter Fluid, then the Carburator is the Problem. Clean and Rebuild the Carburator. If for Some Reason you need to Remove the Flywheel and Change the Flywheel Key, then Send me the Model Numbers Off of the Engine, Please. With these Numbers I can Locate a Breakdown that will Assist you in this Repair. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Respectfully

 John
