Thanks Tom.

The other thing is that even after all my discoveries, it still backfires when I floor it. It is set at factory dwell, 8 degrees advanced, and the mix is still pretty good. But when I floor it, it sputters and either dies or it backfires through the carb. I can't understand why it would do this because it didn't do this before I adjusted the dwell, timing, and mix. I guess I have to just play with the settings? or is there a specific reason for it doing that?
