Dave if you are not getting fire to some holes, I would check carefully for a bent dist. shaft, play in the shaft/ advance, or other related problems. And be CERTAIN the points are actually opening and closing as should be. I hate pulling dist's on slants but you might have to, give it a very close once over.
I have been thinking the same thing since someone tagged Halifax. Im just a little confused on how it happened so quickly. I mean this cars dash, pedals and wires scream that its low miles. How does the dist. get bent?
Ill be checking the gap on those points. I should probably learn the whole dwell thing too while Im at it.
