I just found my inline spark tester and It lite up fine at the end of the plug wire, so it appears I have juice to there. I pulled off the plug connector and no change to the engine . So then I did a dry compression check to eliminate the mechanical possibilities and had 105 lbs there. Then I switched the plug to another cylinder and the miss magically appeared on that cylinder.
So what plug should I use on a 216 with a 12 Volt conversion???
