Push the governor arm [2] away from the carburetor to fully open the carburetor throttle valve.
Hold the governor arm and carburetor throttle valve in the fully open position, and turn the governor arm shaft

Make sure that the clearance [4] is specified value.
Check to make sure the governor arm and the carburetor throttle valve operate smoothly.
Start the engine and warm it up to the normal operating temperature.
Check the maximum governed speed with the blade installed.
