Thanks Everyone!

I was just assuming it was aluminum? There was a very thin hard / brittle coating on the inside dia of the distributor contact points where the rotor contacts the cap.

Once I carefully scraped that off it ran fine.

Now I do still have an overly fast idle to contend with. It is a syncro, so I will try to locate the temp sensors first.

then move on to the tps sensor. I did notice that when I unplugged it and sprayed a little wd40 on it the idle went down to 1K So, I thought it was probably just a bad connection.

But soon went back up. May the computer was adjusting? And yes Scott, I agree! A Subbie is in the near future !
