Het there, everybody. i'm attempting to replace or repair my centrifical clutch on my Motobecane "Super 51" which has the 50cc motor (1977 vintage) I'm a fearin' on the correct way to remove it. It has a 3/8" square insert right in the middle and I've been told just to jam a socket extension in there and hit it w/ an impact gun (in reverse or clockwise since it has lefthanded threads) Is this right?? I'd hate to strip it out if this is not the case. Right now the clutch is locked up so, of course, I cannot stop it without stalling it. Please help me out. P.S I've given up on snowmobiling this year; so I gotta do something constuctive !!
