Ron,

Thanks for hanging in there on this. I appreciate your insight and comments.

Today I installed the electric fuel pump. It made no difference, so I took it back off.
I spent some time setting up a small video camera in the engine compartment to see how the needle rises while driving. I got a usable video, but will work on it more tomorrow. I'll see if I can move the WBO2 gauge from the dash to the engine compartment to be shot in the same frame as the carb throat.
From what I did see in the video I shot, the dash pot seems low compared to your description (mid range). Perhaps I'll see if the springs I have in a set of Euro SU's will fit.

The experiment continues...

-Tracy
