This is the single cylinder Kawasaki engine? When was engine last run?

Technician: Curtis B., Technician replied 1 year ago

Backfiring through the carburetor when cranking, can be a valve that is stuck. Remove the valve cover and check the valve movement.

That is a start, are you close to the mower where we can try this and other test? Would you have a compression gage to see if it has low compression from a valve not seating?

When did you last run the mower?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
I am close to it, but don't have a compression gauge. I started doing this the first time right after it had been running for an hour or so after it had been shut off for 30 minutes or so in December. I put it away for the winter, and now it's doing the same thing.
Technician: Curtis B., Technician replied 1 year ago

Backfire is typically spark occurring when the valve is open. Can you remove the rocker cover and check the valves?

The JD technician said via phone it could be a timing issue with the timing gear. I suppose that could cause improper valve timing too?
Technician: Curtis B., Technician replied 1 year ago

Timing is a possible problem, but I doubt it would be the cam gear. Mire likely would be the flywheel timing key, between flywheel and crankshaft. But I would rule out the valves first! Much easier to check!

Ok, thanks. I'll check that first. Sorry I got nervous when I didn't get a response for quite a while when I was expecting 8 minutes.
