Official Carter Carburetor Form 4960B: Specifications and Parts Listing Model YS950S.

This downdraft carburetor is used on M38A1 (G758). The US Army did not print a rebuild manual for the 950S - use this form and the Service Manual for the WO637S used on the M38 (available here) for complete reference on your carburetor. The carburetors are very similar.
