904 Kickdown throttle pressure adjustment question

I figured this would be more of a throttle issue than a KD. Is there another cable I should be using or is the stock 2bbl cable sufficient for the 4bbl set up?

I can't remember if I used the original 2bbl cable, or had to find a 4bbl cable.

What happens if you move the cable forward a little bit in the bracket ?
If the cable won't let the carb close all the way, then it is definitely to short.
Get the throttle cable figured out first, then go to the kickdown.
