Craftman Kohler Pro 18hp OHV Wont Start / Backfires Thru Carb

I think most all Kohlers use a steel key and won't be sheared. They hold a little less than 2 qts.
Did it smell like it had gas in the oil?
This is common and will eventually cause not to run.
I've seen a lot of the command singles having coils go out recently.
They spark but only about every 3-4th hit and won't run.

All my research on this engine says they are known for breaking flywheel keys. I got the new key, just waiting for ups to drop off the tools I ordered today.

I was right! Broken key! Now just waiting for new carb.
