ABSTRACT:
A fuel delivery system for purging air from the reservoir of a diaphragm carburetor on an internal combustion engine and for supplying priming fuel to the carburetor air intake. A pump is responsive to electrical signals from priming control circuitry to draw fuel through the carburetor reservoir and to feed fuel under pressure to a nozzle positioned at the carburetor air intake. The electronic control circuitry is responsive to an oprator for initiating a priming operation and includes a temperature sensor coupled to the engine for controlling duration of the priming operation, and thus the quantity of engine priming fuel, as a function of engine temperature. A second timer is responsive to operator initiation of a priming operation for preventing regeneration of the priming control signal to the pump, and thereby preventing attempting repriming in the event of failure of the engine to start.
