    You said that you cleaned the fuel bowl. but did you find and repair the reason for the float valve not sealing.

    Sounds like the backfiring was caused by either a sheared flywheel keyway or out of adjustment valves, and this may have caused a blown headgasket resulting in smoking and engine shutdown.

    That what it seems to me , never had one of these engines apart but i have to repair it i have to pull the motor to get to the flywheel . changed many keyways on push mowers , my helpers just loved to try to grind up rocks . will check the compression then figure how to get the motor out
