The distributor cap is almost certainly carbon tracked if there are any

Ben,

I have also had the rotor get a carbon  path to ground.  I was on a high 
voltage system (Datsun 280 Z).  It is  not easy to see this, or test for it, 
but if you have spark going into the  distributor from the coil then either 
the rotor or distributor cap is  defective.  I also have seen some 
distributors that have a clutch drive to  the rotor for ease of adjustment.  (marine 
applications)  Make sure  the rotor is actually turning when the engine is 
being turned  over.
