Description:

This diaphragm operates the carburetor accelerator pump circuit. When the throttle linkage actuates the pump, it displaces fuel to provide a brief enrichment shot during throttle opening. A hardened, torn or leaking diaphragm can cause hesitation and may leak fuel, depending on the carburetor design.
