I'm running electronic ignition, I have them gaped at .046, wonder if I should reduce to the .036. I was just reading that for elec. ign., .04x is the way to go.
there seems to be a love affair with increasing the gap with a more powerful ignition system. i personally don't understand the rationale. maybe someone here will explain it to me.
I run .045 with an electronic ignition and .036 with points. The bigger gap allows for a bigger fatter spark. An electronic ignition has more volts to jump the larger gap.
I have mine at 40, NGK plugs with MSD 6AL box. I don't notice a difference, I was told between 35 and 45, so I set it at 40. A bigger spark makes for a more complete burn I guess?
