    Abstract: 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.

    Abstract: A charge forming device may include a body having a fuel and air mixing passage, a throttle valve and choke valve moveable between first and second positions to control at least in part the fluid flow in the fuel and air mixing passage, and throttle and choke control members associated with the throttle and choke valves, respectively. The choke control member may also be associated with an engine starting system so that the choke valve is moved to its second position upon actuation of the starting system. The choke control member is selectively associated with the throttle control member to hold the choke control member in a position spaced from its first position. In this manner, the throttle valve and choke valve may be automatically positioned in a desired position for starting of the engine upon actuation of the engine starting system.

    Abstract: A carburetor (1, 51) has an intake channel (2) wherein a throttle element and a choke element are arranged with the choke element being upstream of the throttle element. The choke element is displaceable between an operating position (8) and at least one starting position (9). A first fuel path is provided which supplies fuel to the intake channel section (2) in dependence upon the underpressure present therein. A first controllable valve (20) for controlling the supplied fuel quantity is mounted in the first fuel path. In order to achieve an adapted fuel supply in different operating states, a second fuel path is provided which defines a bypass line to the first valve (20). A second valve (44, 54) is mounted in the second fuel path. A method for operating the carburetor (1, 51) provides that the second valve (44, 54) is actuated in dependence upon at least one operating parameter of the carburetor (1, 51).
