Thanks for the replies from both of you. Yep got the  aluminum ball this one  has a pin through the flywheel and shaft whit a setscrew to secure it. I don't know what the other setscrew is for just a backup setscrew I guess. it was running great I did not plan to restore it but the paint came off .I turned every thing 180 degrease today and made no difference .    I worked on it about another five hours today still no go .Any idea would be greatly appreciated
Thanks Stewart
