fleetwin wrote. There are two "timing marks" on the mag plate, one mark is used for "new points", the other is used for an existing set of points, there are two marks on the flywheel as well, one for each set of points. The extra timing mark is used for new points to account for initial rubbing block wear. Sometimes it is recommended to set new points at .022" for this same reason. My question is ? Are these the two parallel marks on the breaker plate ? I have never read anywhere that these two marks are for new and used points. If so would the first mark you come up to be the one for new points. Let me know what is correct. Bill,
