CARBURETER ADJUSTMENTS
If carbureter loads up after considerable service, check float level. Wear on lip of float lever will raise float level. Before adjusting float, be sure float lever pin is firmly seated. Reset float level by bending lip of float lever away from needle to raise level, or bend lip toward needle to lower float level. Bend only vertical lip of float.
If motor stalls while idling, set throttle lever adjusting screw so motor idle speed is that recommended in motor manufacturers handbook. Then set idle adjustment screw to specifications. If these adjustments do not correct the trouble, remove idle orifice tube and plug assembly. Clean tube and passages with compressed air.
