Abstract
End portions of the choke valve shaft project outside the carburetor mixing passage duct. One end portion is connected with an actuator mechanism that is responsive to either engine speed or manifold pressure. The other projects into a cylindrical chamber on the carburetor body that houses a spirally coiled bimetal strip having its inner end connected with the shaft, its outer end engageable with circumferentially spaced abutments. The chamber is communicated with the crankcase breather and also with the mixing duct through a flapper valve, so that the bimetal is subjected to the temperature of vented crankcase vapors.
