Quote:I looked at the inside of the cap and theyre firing right on the edge of the brass terminals. not near the middle, like right on the edge.

When the vacuum advance is hooked up, the rotor has moved away the edge of the brass terminal towards the next terminal. You end up with a large gap between the rotor and terminal.
