This note is for Ross:

I was looking at distrubutor specs in the Packard manual.

For the AutoLite distributors they show 27 degrees dwell.

For the DelcoRemy distributors they show 21-30 degrees dwell. I don't know what that means. Does that mean a steady dwell anywhere between 21 and 30, or a dwell angle all over the map?

I have an electronic dwell meter that I don't use very often. I will test it out and see how it does.

The kernel of the argument here is that the timing light should be steady and consistent. If it varies a lot then the distributor is probably shot.
