Welcome to JUST ANSWER small engines, let me try to help you !! What is the engine model number? 19 hp Briggs? Backfiring is sign a valve is open when the spark occurs. Either valve needs adjustment or the valve is leaking!

Kohler model number? CH, CV, SV, K series? Have you checked the compression and the valves for sticking?
