If carburetor loads up after considerable service, float level should be checked. Wear on lip of float level should be checked. Wear on lip of float lever will raise float level. Bending lip of float lever down will raise float level; bending lever up will lower float level. Only a slight bend is needed.

If motor stalls while idling, reset idle adjustment screw and throttle valve adjusting screw. If these adjustments do not correct the trouble, remove low speed jet tube and clean thoroughly with compressed air. Examine soldered joint in tube for air leaks and see that tube seats air tight in body casting, top and bottom. If not, replace with a new tube of identical specifications. Never change a low speed jet tube from one carburetor to another.

Increased resistance on foot throttle indicates a clogged pump jet. Pump jet should be removed and cleaned with compressed air, which, in many cases, will remove the dirt or lint. All jets and ball checks must be seated gasoline tight.

Poor acceleration may be due to damaged or worn plunger leather in accelerating pump, corrosion in pump cylinder, loose or cracked cylinder, cracked plunger or bent pump arm.

Pump stroke is adjustable for high or low temperatures. Set plunger pin in hole to give longest stroke for cold weather. Set pin in hole giving shorter stroke for hot weather driving.
