ABSTRACT:
A carburetor for an internal combustion engine has an air passage through which air is drawn into the engine, an unbalanced choke valve positioned in the air passage and movable between a closed position and a fully open position, a thermostatic device responsive to engine temperature for urging the choke valve closed with a force which diminishes as engine temperature increases, and a suction motor responsive to engine vacuum for urging the choke valve open with a force which increases as engine vacuum increases. The position of the choke valve at any time is determined by the net effect of the above said forces. A load is applied to the choke valve when it is closed to dampen its movement during cranking of the engine to facilitate starting. Further, the load forces the choke valve closed when it is between its closed position and a predetermined position intermediate its closed and fully open positions. The load has no effect on the position of the choke valve when its position is between the predetermined intermediate position and the fully open position of the choke valve. The closing of the choke valve facilitates restarting of the engine when it is shut down.
