Abstract
A choke system for an internal combustion engine includes a carburetor having a choke valve disposed in a passage; a cooling fan providing a variable air flow; an air vane moveable in response to the variable air flow; an air vane linkage coupling the air vane to the choke valve, the air vane linkage operating the choke valve by the movement of the air vane; a manually operated choke control; an override linkage coupling the choke control to the choke valve; and a thermally responsive member configured to engage the override linkage to retain the choke in a partially open position above a threshold temperature. The choke control may be moved to a first position in which the choke control overrides the thermally responsive member and the air vane linkage to maintain the choke valve in a closed position.
