Carbon tracking through rotor. More HEI woes.

Thanks for all the inputs.
oldkimmer: brass contacts in the cap
Dana67Dart: Going through the center of the rotor.
kitcarlson: Getting an O scope is not practical at the moment. Interesting data. I used the Sun machines, way back. Very useful tool. I will consider a ballast resistor. but that was one of the selling points of having the HEI, no ballast.
Other suggestors:
will definitely look at rotor phasing. And modifying the rotor.

Plugs, wires, cap and rotor are all new. I know that doesn't mean much these days. But all are designed, uh well, marketed as for HEI systems.
