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 plug 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 vertical lip of float only.
If motor stalls while idling, set throttle lever adjusting screw so motor runs approximately 300 r.p.m. Then set idle adjustment screw as instructed above. If these adjustments do not correct the trouble, remove idle orifice tube and plug assembly and clean with compressed air.
If acceleration is not satisfactory remove pump jet and clean with compressed air. Also examine pump link setting. Pump link has three holes giving short, medium and long strokes. If link is set to short stroke, reset to give longer stroke to pump piston. In hot weather, high altitudes, or when high test gasoline is used, connect pump link in innerhole, giving shorter stroke.
Maximum economy is secured only when breaker points, spark plugs, valves and motor timing are set to manufacturer's specifications. After motor is properly tuned, the following should also be done to insure satisfactory performance and economy:
(a) Float level must be set as above.
(b) Ball check in step-up valve assembly must seat and move freely. When reassembling, valve housing must be screwed in tight against seat.
(c) Step-up push rod must move freely in upper and lower guides.
(d) Step-up piston in upper casting should not bind and must be free of dirt.
(e) Main metering screw can be replaced with leaner than standard metering screws, for altitude or high test fuel.
Caution: Do not attempt to gauge metering jets with drills. These jets have been flow-tested, to insure correct fuel flow.
