I have an '85 1.9l with the vacuum advance/retard distributor. I realize the two vacuum ports are connected to different sources of vacuum--the advance (which is teed in with the fuel pressure regulator) comes right off of the center "manifold" box and the retard comes off of the throttle body somewhere (venturi?). I put my vacuum guage on the line that goes to the advance port on the distributor. For some reason, the timing wants to advance and the engine runs faster. This I don't understand at all. How could disconnecting the advance side cause it to advance further? I have 15" Hg at this point. Yes, I have the lines correctly installed. I would appreciate any ideas on this and possibly a quick theory on the purpose of the vacuum retard. Jay |
