Re: Vacuume advance
vacuum advance, is that thing attached to the side of the distributer, and well it has a vacuum line attached to it, when the vacuum pressure is really great, I.E. foot flat to the floor it pulls the timing to more advanced and hence stops the engine going retarded so you maintain power and actually gain a little more rather than loose, to test it, suck on the pipe with the engine ideling the revs should go up as the advance kicks in, and drop back to normal when its not on, other test is rev the motor and stick your finger over the pipe and feel the sucking, or listen for it.
I did put something here, but it vanshied, I think
