Rick, was that to me? If so, I didn't know HEI's went bad like that, I thought they just quit completely, then worked again when cooled off? Or just quit and never worked again. I think my MSD R2R retarded the spark because it never started to miss or anything??? But I'll be damned if I know what could go bad to make it do that?
