Accelerator Pump Stroke
To satisfy the requirements in various climates, the pump discharge can be adjusted. The bottom hole (No. 2) in the pump cam and throttle lever provides the maximum pump discharge for extreme cold weather, and the top hole (No. 1) provides the minimum pump discharge for warm weather operation.
If a change in the adjustment is required, make certain the proper hole in plastic pump cam, located behind throttle lever, is properly indexed with the numbered hole in the throttle lever before installing the retaining screw.
