Throttle Valve
- Remove air intake hose and elbow to expose throttle valve. Loosen throttle valve lock nut on stop screw and loosen stop screw. Ensure throttle valve closes fully.
- Insert a .002" (.05 mm) feeler gauge between throttle valve and throttle housing bore. See Fig 1 . With feeler gauge in position, adjust stop screw so it just touches stop arm. Tighten lock nut. Press stop arm against stop screw and remove feeler gauge.
- Seal threads of adjusting screws and lock nuts with paint spots. Install hose and elbow. Check operation of throttle linkage and adjust if required by ensuring outer cable is secured in bracket so inner cable is under light tension, but not enough to move operating lever. Tighten lock nuts.
