Abstract

See full text

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.
