rebuilding the engine and putting it back together, have wondered about the clutch. One side is a bit glazed it is cork. I have read on the forum that it can be fliped, or is better to buy a new one? Treat has one that is non cork. Also any idea in the rubber grommets.. I have 1 new one goofed the order.. is it better to use rivet or get the other 3? I can't really decide which way is up or down on the new one. Any and all help is appreciated. Stuck at this moment.. have painted and redone everything to this point. Would like to finish but do it right.
