Owner’s Manual

To adjust carburetor, start motor using proper starting procedures, and allow unit to run a few minutes to reach operating temperature. Move Twist Throttle Grip handle all the way off, to idle position. Turn IDLE adjustment screw clockwise to increase motor speed, counter-clockwise to decrease motor speed. When idle speed is properly set, propeller should not rotate and motor will continue to run.
