Another racer with a dirt modified told me he was fighting a miss, I checked his rotor, set his distance, miss gone. If metal tang looks like it has been arcing tang is to low.

I've noticed that MSD has added an instruction sheet with their rotors lately that include the specific rotor tang height.
