This this has been a nightmare, I have searched this site with no luck on an answer.
Problem: Backfiring out the exhust when trying to start, it will start but sounds like a shotgun, then starts and idles rough, pops and carries on then pops real hard and dies. When I pump the ball up it don't get hard.???
I have replaced coils, points (set at .20),condensers, pick up coil under flywheel, plugs (gapped at .30). rebuilt the carb cleaning everything. Checked compression 125 both holes, checked spark with a checker set at 7/16". Woodruff key is good.
I am at a loss here, help please
