That is a good question. I just spent hours this weekend heating and bending the shift linkage rod and the linkage to got it to work smoothly. I will have to jack the car up and take a closer look. But what I can tell you is that with the lever diconnected from the carb I can push it until it feels like the lever on the trans is maxed. I will also check to make sure I am getting WOT from the pedal.
