On suggestions of a few different people on different boards I did some debugging last night.
I reset the Electric choke back to the manufacture default settings
Got the car out and reproduced the problem
With the car running:
I disconnected the throttle cable = no change
manually ran the rpms up to 3000 by hand with the throttle lever and let it re-establish idle = no change
Backed the Fast Idle screw until it no longer was touching to be causing it to hold the idle up = no change
manually ran the rpms up to 3000 by hand with the throttle lever and let it re-establish idle = no change
Took a long screw driver and tried to close the secondary butter-files; they would not close any more = no change
Added a 3rd return spring to the throttle lever but it is connected to another spot from the original 2 springs to make sure there was no interference with them = no change
Again took some B-12 Chemtool and spot shot different areas all around the carb base and intake = no increase or decrease surge
one spot shot into the primary of the carb and a did get a rpm increase for a split second
Looked around the choke area of the carb to try and determine if something was hanging or sticking but did not see anything obvious.
That was all the time I had last night; hopefully this weekend I will get to check the choke area more.
