Thanks JW, my lower body has the correct casting# and stamp underneath, so it is definitely correct for the 2100S. The linkage is stock and should not need modifications as it is a direct replacement for the Roch-B. We're thinking perhaps the throttle rod was installed upside down? or something. None of this makes sense. It cannot work the way it is for sure. In the idle position it has to be around the 4 o'clock orientation.
