Default 73 motor surging

hey everyone, here is what I have been told. First, I have checked fuel pump, plugs, wires, dist., points, vacuum lines, checked for leaks in fuel lines, etc. The car has a carter AFB carb on it. Was told by the previous owner that he had a problem with the motor surging a little over a year ago. They rebuilt the "carter carb" and it ran fine. I have been told by a co-worker that Carter carbs are JUNK and that is my problem. Now, I don't mind spending the money for a Rochester, or a Holley, If that is the problem. HEY FOLKS, WHAT DO YOU THINK?

I would make sure the timing is set correctly first. Use Lars paper as a guide to be sure timing is set correctly.

Check further into the distributor than just the timing. Make sure the mechanical advance has both springs and they are the proper ones.

surging can be an indication of too much vacuum advance on the timing. i'd check the timing setup.
