Default Re: How to convert 2 stroke automatic to manual?

The bolt I'm referring to is not the one that holds the centrifugal clutch to the crank, but the threading in the clutch adapter which is larger that is for the clutch puller. This one will not budge and there was no slipping or wearing down of the crank, so it is very snug. I have a strong grip, but no deal, so I need the puller or one I make up myself which is why I wanted to know the thread size. The pk-80 I'm talking about would be the stock motor which is still supposed to be a very good one even without modifications. I'll do my own porting and my own expansion exhaust. I can buy Jim's head later if I want more power yet. I'll get one this summer regardless even if I can make these automatics work.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
