Re: possible cause for backfiring in single cylinder motor

[benchrascal]

It is bang out the exhaust ,and then something like hydraulicing making it difficult to crank .Lots of resistance in motors that don’t seem to have much of anything wrong with them .I’m going to try to lean the starting mix right down to see if they are trying to gulp too much gas .Very frustrating because up until this point I’ve had very good luck with these motors.
