CARBURETOR ADJUSTMENT

The carburetor has been carefully adjusted at the factory and should not
require any further adjustment. Only the idling speed can be adjusted by
turning the idle speed adjustment screw (see sketch). The correct speed is
2400 - 2800 RPM (or just below the clutch engagement speed ). Turning the
adjustment screw clockwise will increase the idle speed.
If further adjustment is necessary, please contact a local authorized
MARUYAMA dealer.
