Just a comment. I've had two adjustable timing lights over the last couple of decades. The first was a Craftsman I got from Sears years ago, when they were really Sears. That one quit working (the adjustable advance part) after a couple of years. I later bought a medium-priced unit from Amazon on which the advance part never worked. I thought I was inept until I borrowed my neighbor's light which works fine. I returned the Amazon unit and am still mooching off my neighbor. Hopefully, others will have better luck than I did.
