I don't. Shortly after posting the pic I realized it isn't based on the physics of it. The trans rod is too short though and I think and hope that is the trans kickdown issue. Otherwise I don't know.
Have somebody sit in the car and floor the throttle then, from under the hood, push back on the carb lever to be sure it is at WOT then push back on the trans linkage rod to see how much travel is left at WOT; if there's more than 1/8" or so of remaining travel the linkage is the reason for no kickdown.
