Hello,

I can't figure this out!!

My zero turn with 31HP Kawasaki runs fine for a while. In fact, I cut grass for about an hour today with no problem.

Then, it starts sputtering, backfiring, and finally just loses power and eventually just stalls out.

Seems to come back to life for a little while after I let it sit then repeats the issue.

I changed spark plugs, checked carb and it looked clean but gave it a shine up anyway.

Thoughts?

Air Filter? Fuel Filter? Fuel Treatment with ethanol gas?
