I just bought a 1974ish 444 today. There is no serial number plate on it but the engine serial number is 1974. This unit has a starter generator and it won't crank. I sed a remote starter on it at the solenoid and the solenoid clicks. If I turn the motor by hand while doing this it tries to crank. I removed the belt and the starter/gen will run but not very well so I pulled the starter/Gen apart and the brushes are toast. Anyone know where to get a pair. It has a Wilson remanufactured starter/gen on it.
