He also bought a clutch disc and pressure plate. He had talked about clutch being a [censored] size but we didn't realize that it also works backwards of a normal clutch. The pedal is cable actuated with a huge extension spring to keep tension on the clutch fork and pressure plate fingers for engagement.
I did manage to coax the engine back to life for a few minutes but it had a coolant leak in the exhaust manifold area so no test drive at this time.
