If you are working w/the original carb, that could be at least part of the problem. Check the old distributor bushings, vacuum and mechanical advance units as well. The points cam can wear down, too. This will cause timing issues. Set the points by dwell, not w/a feeler gage.

By advancing the timing way out, you are better able to keep a too-lean mixture lit- so if the carb is bad or the engine has a vacuum leak that's bad enough, the advanced timing will somewhat "crutch" the problem of a too-lean mixture. Be sure that the carb is adjusted correctly, if it hasn't been recently rebuilt, it should be.

Get a vacuum gage on the engine and see what the vacuum is at during various running conditions. It should be above 18 at idle, w/the ignition set to spec- but steady. It should drop when you open the throttle, drop under a load but also still be steady.

If you see a bouncing needle, this indicates a miss or valve problem, low and steady could be retarded timing- ignition or cam- etc.
