I would suspect the distributor might be your problem. I’m guessing that you got a remanufactured distributor. If so, I would check the shaft for any side to side play. You need to line up one of the vanes on the shaft with the line down the center of the ignitor, then place a 0.010 feeler gauge in the gap. Then push on the shaft to see if you can open up the gap, this is the only way to see if there is too much play.
