MSD spark plug gap stock 2.4 cis ?
I have a stock 73.5 2.4 cis. I just installed the MSD unit what is a good spark plug gap for daily driving. It says to try out a few and find the one that works best. I'd really like some experienced help with this.
Thanks |

the MSD instructions refer to pulg gap, but a local pope says .040 is the way to go.
I definately wouldn't load my system any more than .040 even if following the directions tempted me. different strokes.......

I ran mine with a .035" gap, copper core plug. Every time I try to use a precious metal plug, it seems like they die an instant death with the msd/mallory :-)

.040" w/ platinum plugs (experiment). So far so good (8000 mi).
