1985 TRX250 Fourtrax: Electric start works fine but kickstart won’t engage, quad won’t move (clutch not engaging) and the clutch adjusting screw (on right side case) doesn’t seem to be doing anything. Would all these issues be 100% caused by a bad one way clutch? Also, the centrifugal clutch drum on my machine looks like it has some black coating around the outside which isn’t typical of the shop manual photos. When I took off the right side case the clutch drum actually looked like it was made out of rubber or black plastic. Is this normal?
