ABSTRACT:
A carburetor accelerator pump lockout assembly having an actuating lever connected to the throttle valve shaft by a pin and cam slot connection, the lever pulling down on an accelerator pump lever upon opening movement of the throttle valve to actuate the pump to inject fuel into the carburetor induction passage; the lever having an extended portion adapted to be engaged by a vacuum controlled servo plunger to prevent pumping movement of the lever, vacuum being supplied to a servo chamber from an induction passage port past a number of flow delay devices that delay the decay of vacuum in the servo chamber for 4-5 seconds upon momentary return of the throttle valve to the idle speed position from the off idle position to prevent operation of the pump while permitting operation of the pump when the throttle valve is maintained in the idle speed position for longer than the 4-5 second period.
