Hey guys, so I pulled the cap on my MSD distributor and the tang on the rotor is a little burnt up on one end, as are one side of all the posts in the cap. I am thinking an adjustable rotor/phasing the rotor would fix it but just wondering if it could be something else. Also, the rotor/shaft also seems to have a bit of play (not getting into the mechanical advance)
I wanted to check the rotor location when firing and I believe I did it correctly but tell me if I'm wrong. Base timing is set at 20 deg so I rotated the engine to 20deg on the balancer on the #1 cyl comp stroke. I then made a mark on the distributor body (black marker) to mark the location of the #1 cylinder post on the cap. The tang is at the far end of where the post on the cap would be and once the mechanical advance is added gets even further away.
