I have covered this topic in a prev thread but did not ask this question. I want to put a new vac motor in the snorkel. Is it the same for a 2b v 4v carb set up? Short of using a cav pump I have tried the tests suggested here in my prev thread. I come away thinking that motor is bad. It is VERY stiff to move, very stiff. I think it is just seized up to an extend. I assume any gm breather would have the same one on it?
