Trans Kickdown Linkage Guru Sought
Looks like my Frankenlinkage and attempts to get the K/D to work properly are back in focus.
... I stand by my position that this throttle adapter alone will not cure all the linkage issues he has. Did you look at his pictures of how the throttle cable is already so far in it nearly touches the carb now? How would it possibly work when adding another part that moves the cable out even farther?? By then the cable would be at a 45 degree angle to the linkage! He may need this part but he needs the correct throttle bracket first.
This thread has been kinda confusing, to me at least. Part of the confusion comes from the first two pics I posted back at the start of the thread, and the well intended comments from folks who know much more than I. The first pic was "as found" Edelbrock 1406 and throttle bracket and kickdown linkage pieced together from unknown parts, no Eddy adaptor, and parts bent to sorta work. The carb stud was at the front of the K/D rod, and I didn't know any better.
I blacksmithed the throttle cable bracket to align the cable with the TQ linkage when I retired the Eddy carb.
The second pic is just a couple of weeks ago. The ThermoQuad is a good bit wider than the 1406, and has the correct linkage. No adaptor needed. The discussion then centered on the length of the K/D rod and I tried to lengthen it with the fitting on the end. It would only go about halfway back, as the pic shows.
As the knowledgeable contributors said, the carb stud needs to rest at the back of the slot of the end piece of the K/D rod. I found another adjustment point on the intermediate rod that runs from the upper to the lower bellcrank. Tweeking that effectively lengthened the upper rod so the carb stud now rests at the rear of the slot, and the rod moves toward the firewall when the throttle begins to open.
Johnny D's beautiful pic shows the intermediate rod with the adjustment at the upper end. It also shows the angle of his upper bellcrank to be much narrower that mine. In fact his bellcrank is much narrower than mine, which is as wide as the valve cover and the angle of the two arms of the bellcrank is quite different.
The first pic is the alignment of the throttle cable and the TQ. The second is the bracket and upper bellcrank that was on the car when I bought it, and still is. I hope that helps.
