Vacuum advance removal, is it possible?
Good job. Only one more thing you want to check. ROTOR PHASING You can google this, but essentially you take an old cap and cut/ drill the cap so you can see the rotor near the no1 plug tower.
Just run the engine with a timing light and play with the throttle to change the advance. The rotor should "make spark" withing the "envelope" of where the rotor end contact is brushing past the tower contact. The "perfect" setup for no vacuum would be when the spark fires and the rotor and tower contacts are CENTERED with very little movement
(Vacuum advance changes rotor phasing, mechanical should NOT)
