  1. Slide the throttle shaft into the body and fit the throttle plate to the shaft. Centralize the throttle plate in the throttle bore with the throttle plate in the closed position. Be sure that the two indentations in the throttle plate face the same way as the screw head recesses in the throttle shaft. Engage and tighten the throttle plate retaining screws.
  2. Replace the throttle stop screw and spring.
  3. Install the accelerator pump lever to the throttle shaft.
  4. Connect the accelerator pump rod and spring assembly to the arm and to the pump operating lever. Fit the diaphragm plunger into the accelerator pump cover.
