have someone press the gas pedal to the floor (or wedge it with a pole/bar etc) while you check at the carb that you actually are getting full throttle. that's what it sounds like to me.

I was reading a LONG thread last night on here FABO. That is going to be my first check. I am trying to find a diagram of my specific set up for the throttle and kick down linkage in the Service manual.
Reading some of these other posts I am glad I am not afraid of a tool box, and am willing to learn.
