X304 Slight backfire at idle.
Hey everyone, just curious if this sounds normal. I previously had an X300 with the same Kawasaki engine, and I don’t remember it having this slight popping sound at idle.
As soon as you give it any throttle, the sound goes away and the engine seems to run normally. It was also just serviced with a new air filter, engine oil/filter, fuel filter, and spark plugs.
I only run REC-90 ethanol-free fuel in my tractors, so I’d be a little surprised if it were a carburetor/fuel issue.
Any suggestions, or does this sound completely normal for these engines? Curious what others think. Thanks!
