Abstract
Apparatus (1) for controllably opening the choke valve (V) of a carburetor (C). An actuator (3) is supplied signal elements of an electrical command signal. The actuator is responsive to the command signal elements to move a choke shaft (S) and open the choke valve. A spring (13) is connected to the actuator and the choke shaft to exert a choke valve opening force on the choke shaft when command signal elements are supplied to the actuator. A sensor (21) senses the temperature of the engine and generates an electrical signal representative thereof. A processor (23) processes the electrical signal from the sensor and generates and supplies signal elements of the electrical command signal to the actuator if the engine temperature represented by the electrical signal is less than a predetermined engine temperature. The choke valve is fully opened when engine temperature reaches the predetermined temperature.
