The W-1 on my 38 coupe has the same carb as in Brendan's picture. It's stock from the factory. There may be a difference between the car and truck carburetor. The only thing a kit will give you that you don't alread have is gaskets and an accelerator pump plunger. The brass washers for the brass plugs won't seal and keep the gas from leaking out. Carbking advised me to put a drop of blue loctite on the plug threads to seal them. If you don't have broken or missing parts (like the plunger) you don't need a kit. The kits cost around $50 each. Clean the carb in carb cleaner, re-assemble using loctite on the plugs, make a new bowl gasket using rubberized gasket material and you should be good to go. You can get kits at Chevs of the 40s, Obsolete Chevrolet Parts and The Filling Station. Obsolete Chevy Parts and The Filling station have W-1 kits for both the flat shaft accelerator pump and the round.
