An air/fuel mixing apparatus configured for use with an internal combustion engine including a carburetor including a body defining a passageway therethrough and a choke valve positioned in the passageway, a solenoid, and a thermal switch configured to energize or de-energize the solenoid. The solenoid is configured to move the choke valve between the choke open position and the choke closed position, wherein the solenoid includes a rotary shaft coupled to a choke lever, and a thermostatic element coupled to the rotary shaft. The thermostatic element expands and constricts based on a temperature of the engine and restricts the movement of the choke valve between the choke closed position and a partially-open position when the solenoid is not energized.

Engine

An air/fuel mixing apparatus, configured for use with an internal combustion engine, includes a body defining a passageway therein, a throttle lever including a cam surface, a throttle valve positioned in the passageway and responsive to movement of the throttle lever, a choke lever including a follower surface configured to be engaged by the cam surface, and a choke valve positioned in the passageway and responsive to movement of the choke lever and the throttle lever. The air/fuel mixing apparatus also includes a solenoid configured to disengage the choke lever from the throttle lever, and move the choke valve to a substantially-opened position.
