1. If memory serves, there should be a water spray out of the exhaust relief holes, about half way down. If it sprays at slow idle, it probably is ok. Rotor should be a close fit on the eccentric cam and be a close fit depth-wise in the housing. There should be a gap between one side of rotor and the housing. The gap moves around as the rotor wobbles through it’s rotation..
Maybe this will help—
