Hey everyone
Installing a new piston on a Stihl MS391 here, and wondering why I keep having a "stiff" and not "loose" moving piston on the crankshaft top (connecting rod) bearing/needle cage. Bearing/needle cage itself seems fine, but when pressing in the piston pin, it is hard to move around.
Any tips?
