Adjusting the Carburetor
Your carburetor does not have a high-speed adjusting screw (H screw). Adjustment of maximum engine speed is not necessary. The carburetor is set at the factory to provide an optimum fuel-air mixture under most operating conditions. Idling and part-load emissions are minimized by limiting the idle mixture.
Adjusting Idle Speed
Engine stops while idling: Check standard setting. (L screw must be one turn open) : Turn idle speed screw (LA) slowly clockwise until the cutting blades start running and then turn one-half turn counterclockwise. Cutting blades run when the engine is idling: Check standard setting. (L screw must be one turn open) : Turn idle speed screw (LA) slowly counterclockwise until the cutting blades stop running at idle speed and turn the screw about another one-half turn in the same direction.
