I know the mixture still needs adjusted since I replaced the fuel dist and it's rich. I pulled the plugs and they were heavily carboned black. Cleaned them all, leaned it out a bit and most of the surging went away. Just down to a lumpy idle.
Tried using a friend's old Sears diagnostic station but the dwell needle didn't change when tuning the mixture.

Sounds like you are doing the right stuff; except for the dwell meter. The dwell meter is used to set up points in a non-electronic ignition vehicle. Adjusting the mixture won't show on a dwell meter at all.
Does the diagnostic rig have a fuel mixture guage? The ideal mixture should be 14:1 Or if the machine has a c0 meter, somewhere around 1.5 to 2 5% would do it.
