1. Start the engine and allow the engine to reach normal operating temperature. 2. Loosen the nut on the side of the governor which holds the compensation adjusting pointer. 3. Manually move the pointer to the extreme upper position and tighten the nut. 4. Remove the plug from the base of the governor. 5. Using a wide blade screwdriver, engage the wide shallow screwdriver slot and turn the needle valve 3 or more turns counterclockwise.6. Allow the engine to surge for approximately 30 seconds. This will allow the governor to be purged of air.7. Loosen the nut and move the compensation adjusting pointer to the extreme downward position. Tighten the nut.8. Slowly turn the needle valve (wide shallow slot) clockwise until the surging stops.9. It should now take less than one turn from this point to close the valve completely.10. Open the valve to the same position where the surging had stopped.11. Manually move the governor linkage to disturb the engine
