I can't seem to locate comprehensive guides on how to diagnose problems. Right now i have a clutch problem. The clutch has play when car left sitting but once it drives a little the play disappears and after about 10 kms the car won't move because, i assume, clutch slips. The clutch was replace 200 kms ago. The adjustment nut leaves about an 1/8th of an inch of thread on the end of the push rod.
