ABSTRACT:
A dual carburetor system employs a main carburetor to supply a lean mixture to the main combustion chambers of an engine and an auxiliary carburetor to supply a rich mixture to the auxiliary combustion chambers of the engine. Each carburetor has a choke valve operated by a thermo-responsive device. Each carburetor has a locking lever which cooperates with an element connected to its choke valve to lock the choke valve in open position. A device responsive to temperature of the engine coolant operates a single member which moves both locking levers to locking position upon increase in temperature of the engine coolant.
