thanks for the free wheel info. im not sure if the problem is at the rear wheel though. the pedals dont move the chain at the front end.
also, im not sure the problem with the drive train is the clutch. i can get the engine running, and the drive pulley spins, but it just spins on the axle. i took it off and just looking at a diagram online, it seems a key was missing. there was no part in the groove on the axle. i think it was only transferring power b/c the drive pulley was cranked down too tight. how can i diagnose if it was for sure the clutch or this apparently missing key?
