Thanks for all the help, I didn't get to work on it yesterday, and now it's back to the real world so it will be a couple of days before I get back to it. From all I'm hearing, I must have a ground wire broken inside the distribitor somewhere as the points do not ground out when closed. I'll dig into it further some night this week and let everyone know what I find. I'd run home and do it now but this darn job keeps getting in the way..
Enjoy, Joe

Yeah, one side of the points should always be at ground voltage and
the other should go up to near battery voltage when the points are
open and go to ground voltage when they're closed. I worked on a
forklift recently that had the wire from the mounting plate (which was
tied to a broken vacuum advance assembly) to ground broken off.
We replaced it with a piece of Solder-Wick and a couple of crimp
terminals. Between that, fixing the vacuum advance and freeing up the
centrifugal advance, the forklift went from barely running because of
"a bad carburetor" to purring and reliable.
As Farmer says... check the grounds. :)
