Attached are pictures of the Marelli rotor and distributor cap from a 1970 911T. These parts only have a couple hundred miles on them, They replaced a set with several hundred miles that were similarly burned albeit not nearly as badly.

Engine is stock with the exception of an MSD box. Parts are from PartsKlassic. Kurt suggested checking the phasing of the rotor (which, even after reading what this is, I don't know how to do with this set up)

Any ideas what could cause this level of degradation, especially with an electronic ignition I'd be grateful. Engine is currently apart.

Thanks-RickO
