Engine Backfiring

[RGilliam]

Ive got a 20hp honda that has been running rough the past few times. Today I ran it, I'd let off the trigger, and it would backfire. The other day, it ran a couple hrs, then finally died on me. I drained the gas, thought that may be it, but it didnt clear it up. Any suggestions on what it could be?

Air filter, spark plugs?

Air filter seems fine, Im going to try spark plugs tomorrow. hopefully that may fix it. cuz I need it this weekend and i dont have time to bring it to you, trucks going in the shop in the AM tomorrow

Its the carburator change it and you should be fine.

Start with the plugs and air filter like Russ said. Many times if it has a lot of hours it may need a valve adjustment too.

I have the same problem with my Briggs. I spray some carb cleaner in the inlet to the fuel bowl and intake. Seems to work.
