Valve 318 question
two photos below. first is on an STR-12 but it shows the type of spring that is stock for 1970 - runs from the kickdown pivot on the throttle bracket to the throttle stud on the carb (not on this one cause there're two carbs). Second photo is a different type of rod (I think stolen off a truck motor) it has a tab on the rod with a small spring to the throttle stud on the carb. The advantage here is that the rod is longer than a 318 rod and so you don't need the extension for the rod. The whole point of the spring is to hold the kickdown forward.
I believe the slot in the end of the assembly is so that when you let up on the gas, the kickdown rod is not jerked into place with the throttle, but rather returns to that position on the pull of the spring. That's why I have always avoided the bolt in the slot deal. Can anybody confirm this?
By the way it looks in the photo that your throttle return springs (applauding two springs!) seem to be next to one another and sort of twined together. Usually you put the small diameter spring inside the large diameter spring so that each spring operates properly (see second photo)
