John Deere 245 (14 hp Kawasaki engine) - backfires through muffler

[junkman hobson]

Any suggestions on why this engine keeps backfiring through the muffler? Has new igniter. Thanks

Is it a liquid, or air cooled Kawi?

Your anti fire solenoid on the bottom of the carb could be stuck in the open position if fitted.
On the bottom of the carb bowl will be a electrical wire which connects to the solenoid.

It is single-staged - - air-cooled. Thx
