I bought a clutch a couple years ago and just got around to putting it on a motor this week. I paid a small fortune for it since it's for a 1 inch shaft. Anyway, when I pull to start the motor the clutch is already engaged! I have to get back wheel off ground to start it. This clutch looks well made and is heavy, but seems like it's junk. Is there a way to fix this? Anyone ever heard of this? Thanks!
