Re: Pertronix Ignitor II and Flame thrower II coil
The two advantages to the Ignitor II is the power off feature and adaptive dwell. If you leave the key on/engine off with the original ignitor, it can be damaged. The Ignitor II senses this and turns itself off. The adaptive dwell is supposed to make starts easier by adjusting the dwell to provide more spart when turning the engine over (my understanding). The II costs about $30 more, but well worth it for those reasons. <br /><br />As for the coil, I opted for the standard flamethrower coil and have not been dissappointed. My original col was 1975 issue and was on its last legs.<br /><br />If you go for the hotter coil, which I recommend, be sure you have decent wires. My wires that I pulled last year were 1975 issue as well. I installed a new $35 set of MagStar marine wires and really like them. They have much more insulation.<br /><br />This years spark plug change will also get the .05 gap increase recommended with the ignitor and flamethrower combo, so I'm curious if there will be any change in running.
