Kohler KS540-3011 Backfires through Intake
1. Last used my Cub Cadet (model 13A0A1CS056) riding mower without a problem
2. Parked it for about two weeks
3. Tried to start it, cranks strongly but no start and . . .
4. Backfires explosively through carburetor
5. Check flywheel key - intact and no apparent problem shifting
6. Checked electric solenoid valve at bottom of carburetor - activates w 12V jump
7. Took off valve cover - rockers are operating when engine is rotated
8. Checked spark with tester on plug. Good spark
9. Removed and cleaned carburetor. Reinstalled.
I’m at the end of my knowledge base. Any and all suggestions will be greatly appreciated. Thanks to all.
