Here's a quick trick- - - - -if it's got the "window" type distributor with the sliding adjustment window for the points. The points are held in with 2 screws and the point assembly is slotted, so the screws don't have to be completely removed to change points. Take the points out, and use an emery board or fine-grit sandpaper to clean the contacts, then wash with lighter fluid, alcohol, or some other quick-drying solvent. When you reinstall them, use a business card to guesstimate the gap, with the rubbing block on the high point of one of the cam lobes. Once it's running, turn the adjusting screw clockwise with a 1/8" Allen wrench until the engine stalls. Back the adjustment out exactly 1/2 turn, and the dwell will be adjusted to 30 degrees. Chances are the only problem keeping it from running is a set of dirty points. Good luck!
