How to Hook Up a Throttle to a Marine Carburetor

When you hook up the throttle on a marine carburetor, you're connecting the throttle lever and a throttle handle. You are using a marine control cable -- a length of wire encased in a plastic or metal sheath, to make the connection. You are controlling the amount of backlash, or excess cable, by adjusting the distance between a fixed fastener, called a trunnion, that holds the sheath, and the throttle lever.

Instructions

    • 1

      Snap the throttle cable's end to the throttle lever, by hand. Push the throttle lever against the idle stop screw. Hold the throttle lever in this position.

    • 2

      Adjust the cable trunnion by hand so it will slip into the recess in the cable anchor bracket.

    • 3

      Press down on the trunnion to lock the it into the recess. Move the throttle handle. If the throttle lever is tight, adjust the cable trunnion in the recess.
