52.0.7 Carburetor
The correct GPW carburetor is a Carter model 539S also known as type W-O. The carburetor bowl, cover and horn are natural finished cast zinc (not gold).
The cast iron carburetor base is not drilled and tapped for a pipe plug as are the later civilian carburetor bases. The base is finished with a black chemical treatment similar to S2, it is dead flat with a white or gray tinge.The throttle shaft lever, throttle arm, rod, choke link, choke lever and all hardware are cad plated. The metering control rod is retained at the throttle arm with a bayonet-type washer and spring which is usually missing or replaced with an incorrect substitute. Most carb parts are marked with a Carter “C” logo and the Carter part number.
The carburetor is mounted to the intake manifold with two 3/8” hex jam (thin) nuts and split lockwashers, all S2 finished.
The carburetor linkage is painted gray with the exception of the return spring which is S2 finished.
