Kohler 16hp stopped running...won't start

Hi All,

As if I didn't have my own mower problems. LOL. My neighbor brought his John Deere over for me to look at. He has owned it for 5 years and had no problems. He pulled it out of his shed yesterday, it started right up and he drove it to the front yard. He engaged the deck an that's when it all went downhill. It started running rough and died. Now when you try to start it, it just backfires. I checked what I thought could cause the starting problrems. It has strong spark, fuel pump is working good, has good compression. I can hear the fuel solenoid click when I turn on the key. I put a shot of fuel in the spark plug hole, just a bigger backfire! It sounds like it is a timing problem, I just thought it was odd that it came on all the sudden. Flywheel key should be good since it was running good and mower deck wasn't on when it died. Any other possible solutions would be greatly appreciated.

Engine numbers are
model CV460S
type 26513
code 3212809043

Thanks,
Cory

 

I got it figured out. Decided to go ahead and pull the flywheel and check the flywheel key. Lo and behold it was sheared. Problem solved. Glad it was that easy.
