I am going to address the last portion of your post. If the distributor shaft is worn in the bushings where the shaft comes through, or is bent, or has some of the cam lobes worn down, it will run on only one cylinder, (or none, or all of them erratically). With the rotor removed, Try to wiggle te shaft toward the engine and away from it, Up and down, and diagonally. If you detect any movement you can feel or see easily, it is time for a rebuilt distributor, or to have bushings put in yours. The tolerance is at or less than .001". Worn bushings allow radical timing changes and dwell changes than can prevent spark to some plugs. I give it a 90% chance of being the issue. Setting the point gap at like .030 might get some more cylinders operating, but that is not going to fix it, just a possible check. Putting the distributor on a Sun Distributor machine will tell the story. If the bushing is bad no other help will be effective. Jim
