The best spark setting for mixed use is not, ever, a single position. Beyond a certain RPM, and assuming WOT, a single setting is very close.


Bought it that way thinking I had a start retard and it wouldn’t be an issue. Wrong!
MSD digital 6 manual says it retards timing 20 degrees. I guess I also planned for this car to be race only, but now
I’m getting some street use out of it.
