Got an email with some info from the 2nd owner of the car. He had he same problem and was convinced it was electrical in nature. The car acted this way on a number of occasions when I first got it. I have sinced changed the carb to a #'s unit for originality. And it still does the same thing, but it seems worse. I am really starting to think there is some wire that is pinched on braking, or .....??? went for a ride tonite and it screams down the road, but come to quick stop and.....that's it! I plan on jacking up the car and checking all wires near the back of engine, harness, etc.
