Rebuilding a Carter W-1 for a club member who has a '32 Chevrolet Roadster. I found all the parts I needed at Mike's Carburetor: https://www.carburetor-parts.com
The W-1 has 4 fuel circuits and 10 cleanout plugs. Unless you know the carburetor is good, I would remove everything from the cast iron base and clean all the passages. Too much of a chance for rust in those passages if the carburetor has been laying around unused. Good luck.
