Procedure

1. Hold governor lever away from carburetor so throttle lever is against idle speed (RPM) adjustment screw of carburetor.
2. Start engine and allow to warm up, then adjust screw to set approximately 1200 RPM. Check speed using a tachometer.
3. Turn adjustment screw (inner) clockwise (in) to increase or counterclockwise (out) to decrease speed.
4. Release governor lever and check that throttle lever is in idle position.
5. Turn governed idle adjustment screw to obtain equipment manufacturer's recommended idle speed (1500-1800 RPM). Some engines have a bendable tab that is used to set this speed. A pliers should be used to bend this tab to achieve recommended speed.
6. Move throttle lever to wide-open/full throttle position and hold in this position.
7. Turn high speed screw to obtain intended high speed no-load RPM. Governed idle speed must be set before making this adjustment.
