Well it seems I have done the impossible then. I never heard that you can't use a dial-to-zero timing light with an MSD system. I have set my timing several times with my Summit bought timing light (sorry, don't remember the brand) and I have an MSD-7 digital box. The dial-to-zero feature was really handy.
Why do you guys say don't use this timing light with an MSD?
