I have a cheap one button tach on my Stage 2 212 that i recently built. It was reading fine with the stock flywheel and tach set on 1P1r (one spark per revolution). I have a billet flywheel now and every now and then it will stop reading, then come back a second later. Im wondering if I should set my tach to 2P1r? The billet flywheel has two magnets on it, right? Sorry for the silly question, I just want some more opinions
