ABSTRACT:
A mechanism is provided whereby the opening of an automatic choke valve is controlled by means of pressure in a diaphragm chamber with the chamber being selectively communicated with a vacuum pickup tube or an atmospheric pressure pickup tube through operation of a solenoid controlled valve. A switch actuatable in response to vehicle speed and another switch actuatable in response to engine temperature operate to selectively connect the solenoid controlled valve to a power source thereby to determine the operating mode of the valve.
