I understand the need for the remote control parts and cables. What I don't see in the diagrams of the tiller version and the remote version are the differences where the throttle rod connects. I know on the tiller there is a drum the cables from the tiller rotate by a pull pull system. On the remote diagram I don't see what replaces this. On the tiller diagram I don't see this part shown. It seems this section of parts is missing on both diagrams. Or am I missing something.
