How do identify what year my engine is?
Two things I note...
Left circle... The kick down should be touching the rod that goes through it.
Right circle, is the spring attached to the kick down lever. It's only use is to keep the lever in contact with the throttle linkage. The slot is to allow the throttle to return to idle should the trans lever get stuck
The adjustment should be with carb at WOT the kick down lever on the trans should just be fully back.
Do you have the correct 4bbl vs 2bbl arm on the trans?
