340 Chugging instead of Reving
[1] The centri curve is going to move the rotor position as it fires. Same with the vac adv. The dist will be made so that these movements are centered around the matching terminal in the cap.
[2] The firing point of the p/up is just as the trailing edge of the reluctor tip passes the pole piece.
[3] The thick reluctor is junk, looks to be stamped not machined, the thick tips gives imprecise timing. Don't know why fools buy this junk.
