18. Tighten the screw. Start the engine and confirm
that the engine idles at 1,200 RPM and reaches
3,850 RPM at wide-open throttle.
19. Test the operation of the vehicle in a safe area
that is free of obstacles, hazards, or by-standers
before returning it to service. If the cable and
governor adjustment methods are unsuccessful,
engine performance issues or parasitic loads
must be fixed before adjustment will be effective.
