So, i completed all the things discussed in the above posts except the carb replacement.
The car runs 90% better than it did before. No more backfiring. The two things that made the biggest difference were verifying the timing was correct and changing from reistor plug wires to solid core wires.
The addition of the timing pointer was a big help. I cut a small notch in the crank pulley with my Dremel grinder and put some silver paint on it.
