Fuel System

From the 1938 Chevrolet Passenger Car and Truck Service Information

Carburetor changes for 1938: bowl balance passages through the choke shaft and air horn, a relocated bowl vent in the accelerating pump tower, a one-piece choke valve, and a spring-loaded choke lever linkage that prevents over-choking and absorbs backfire, plus a new metering rod and .095 inch jet.
