I have a 1972 Corvette that I put a 700r4 transmission in and have a question. I have been trying to adjust the tv cable as everyone has told me to Push down on the release tab and push the center tab in on the end of the cable, then go to full throttle and it should then set the cable to the correct setting meaning the center tab should click into place. Mine is free and moves easy, its a new cable and its being put on an Edelbrock duel guad carb setup. However it doesn't click out at all, no movement. Does that mean that it's set and doesn't need anything further? Or does it mean that the throttle lever and tv cable end aren't traveling far enough? I have went so far as to pulling on the cable end to see if it will click out and it does.
