As far as ported versus manifold vacuum advance problem, i strongly think it's because my vacuum advance canister is putting out too much vacuum (advance) and. Using a limiter plate to prevent the vacuum advance from adding more than approx 12 deg of timing is the best trick you can. I could see where it could be. Contrarily, the manifold vacuum affects the ignition timing. There's been a lot of debate whether or not the vacuum canister should be plugged into a ported or direct vacuum source. A manifold connection will register vacuum. As the pedal is pushed, the vacuum increases. Ported vacuum pressure is low during idle and does not affect ignition timing.
