ABSTRACT:
A choke for use with a carburetor on an internal combustion engine comprises a housing having an air inlet and an air outlet the air outlet being adapted for communication with the air intake of a carburetor. A valve means within the housing includes a valve member and means biassing the valve member in a direction to block the passage of air between the air inlet and the air outlet of the housing. The valve means is responsive to engine vacuum during starting of the engine to move the valve member in a direction against the biassing means to permit air to enter the carburetor from outside the housing via the air inlet and air outlet thereof.
