The distributor is points style with H.E.I. conversion kit. What it's doing when rev engine up the distributor is advancing and staying advanced. Will not return. This problem causing engine run hot. And when you pull up to light R.P.M. were up. Found problem today with nephew was holding light on tab. Also explains ignition breaking up at higher R.P.M. . Problems been pain in a## lately. Fix one find another.
Is the advance plate sticking? Is your vacuum advance hooked up to the ported nipple on the carb? Maybe the springs on the plate are weak or broken.

I had a car that ran erratically one time and finally changed out the distributor, it cured the problem. Found out the bushings were worn allowing the shaft to wobble. Maybe you are right, it might be time for a new one.
