So I measured mine tonight and it was 17 1/4" from the end of the ball to the offset that attaches to the bracket on the side of the block. This would not let the carb open up to full throttle. I decided that I would modify the rod, so I cut it open and spliced in a 3/8" added length. This now allows the carb to fully open. I now tested the truck with it sitting for a few minutes after stopping hot and it restarted by putting the pedal to the floor. This is PROGRESS!!
