Hi all, My son has bought an AE71 sedan and we were trying to give it a tune up, but the vacuum advance on the dizzy dosen't seem to be working, there is no difference with the hose conected or disconnected-no rev change. I was wandering if anyone had a schematic or a diagram of the vacuum or polution system so we might be able to find out what the problem could be or maybe some advise. Cheers, alot of help already gathered by just visiting this sight but so I thought that we should join up. :)
