Ballast resistors are used to allow full 12v when cranking then lower voltage right away as coils are based on 6v systems to save the points from metal transfer which you could see. If those fail you generally get a start but engine will not stay running right when you let go of the start position of the key. The other way they fail is engine cranks like crazy then runs when you let go of the "start" position. These things were not that common but the car is older now too. Older alone shouldn't really be the issue here. I have right now a 1948 mostly GM style engine that runs fine. Original coil, distributor still work fine. Needs the points plain cleaned with a point file now extinct too. You used to adjust points with a small tool looking at them thru light before putting them in. Nobody did that so they didn't last for crap. You don't play with the adjustments of dwell or timing but rather get it right. New points mean you could change the timing so you check that when they have been changed or replaced. This stuff must be known right so you can forget it and move on to why this car doesn't run properly. You might have a fuel problem with the carb or even an exhaust restriction. Virtually all 1983 vehicles at least sold to the US had catalytic converters which by now might be clogged and you can see that with a simple intake manifold vacuum test. Say it sets at 18Hg at idle. Raise idle to 2,000 RPM and it should still be the same. If lots lower you near certainly have an exhaust restriction, engines may run fine but lack power if so. This car is still on the newer side but basic checks to rule things out. I haven't seen you "dwell" reading yet or if it fluctuates. You can "time" an engine by knowing what intake manifold vacuum should be and get close but not that precise. I/we don't know for sure what the problem is but so far not much has been ruled out. That's what mechanics do with funky problems. If you are convinced ignition is all right then get out a vacuum gauge and let's move on to other possible problems........
