Sorry, I guess I just felt a little piled on.
The car ran fine for a few months with timing set right where it is. Then started acting up. Something had changed besides the initial timing, causing the issue. We did try more initial back when I started the thread, and it would just die.
It was pointed out earlier in this thread that the Pertronix might be at fault, which was in the distributor when I bought the car. I know nothing about them, but after doing some research on this site found they act up sometimes.
Yes, I like to do everything myself, but I have work to do on three of my old cars this winter, so threw in the towel on this one, and sent the distributor out.
