ok, here is what is going on. the vaccum hose u r using is placed in the wrong spot.

u hooked it up to a place where vaccum is there 100% of the time, which is used for everything BUT the distribitor. There should be a line that only has vaccum when the carb is opened up to a certain spot. Easy way to find it is get a vaccum gauge, and look for a line coming from the carb that has no PSI. hook up the gauge, and rev the motor a few times (while running of course) and u should see psi build as the revs go up.

this should let u be able to properly time ur car.
