Abstract

See full text

An internal combustion engine that includes a carburetor having a choke valve and an actuator configured to move the choke valve between a closed choke position and an open choke position. A passageway is configured to direct a pressure pulse from the engine into a fuel chamber of the carburetor. The engine further includes a priming valve at least partially located within the passageway. The priming valve is configured to move between an open primer position that allows the pressure pulse to enter the fuel chamber through the passageway and a closed primer position that substantially restricts the pressure pulse from entering the fuel chamber through the passageway. The priming valve is configured to move between the open primer position and the closed primer position by the actuator when the actuator moves the choke valve between the closed choke position and the open choke position, respectively.
