I thought a little more about this. Since the engine was running fine, but then started spitting back thru the carb, I would suspect that some carbon or other gook is holding the intake valve open a little bit. I would pull the head and try blowing into the carb by sealing the air intake with my lips when the intake valve looks closed. If the carb/intake will not hold pressure and is leaking around the valve, the problem would be found. I suppose a valve could also get bent somehow, but I really don't know how on a flathead??

I had a real hard time getting the flywheel off my engine. 20+ years makes parts bond to eachother pretty well. I had suspected a sheared key, but it was fine. I could see why an engine would not run if the ignition timing is wrong, but don't see how wrong ignition timing would make an engine spit back through the carb. But I sure could be wrong.....

Always lots to learn!
