dual point distributor

Chewy,
Do you do that while the car is running? blocking off the 2nd set of points i mean. The car runs until i apply vac. to it. Then it just shuts off.. I dont really get the point of the dual point ignition. Is electronic ign better? I would assume so. I do like have the original dist that came with the S car. I looked at the wires last night and saw very good tight connections and no corrosion or dirt...I spun it and watched the points and one would close just as the other would open, but thet were never both open at the same time. Does that mean anything?...I didn't put a guage on them to measure the gap...I'll do that tonight.

You block one side when the engine isnt running. Have to have cap off. If you have one set blocked off, and the vacuum still kills the car, It really sounds like a wire short within the distributor.g

Vacuum advance moves the breaker plate, which if you have an intermittet short, when it moves, it could either be breaking a connection, or shorting a connection.

Dual Point Vs Electronic ignition is a debate that has pro's and con's on both sides. Personally, I like the way the dual point runs better. ONce dialed in, point adjustment for me was 5 years in-between.

Initial setting, .017 or .018, but still have to dial in the dwell.
