Need help for friend who is not going to be around long

I'll try to help.
Might seem odd but does the car have points? I had a similar situation where the condenser was bad a $3.00 part was running but rich black smoke and surging on load. I rebuilt carb. No change, then new fuel pump no change, new generator no change. New points, no change
New condenser runs better than new! Couldn't go past 65 without hesitating and stumble, new condenser runs 109 mph without hesitation.
