Electronic ignition on one side, mag on the other. Mags have crummy sparks.

I run UREM37BY massive electrode plugs initially gapped to .016" on my Slick mag.

I run NGK BR8ES auto plugs (snowmobile, jet ski, what have you!) initially gapped to .034-.035" on my Lightspeed Plasma II electronic ignition.
