"complete rebuild kit" is a term that is quite misleading (the word "complete" has different meanings to different individuals")
This was a term that was supplied by some of the aftermarket kit manufacturers back in the 1940's and 1950's to try to get an uninformed customer to buy their product.
The carburetor companies used the term "major rebuilding kit" for their best kits, and something like "zip-kit" or "clean-out kit" for their basic kits. The only commercial aftermarket company of which I am aware that ever sold major kits was Standard Hygrade, who sold a kit called a "contain-all" kit (not to be confused with their basic "Jiffy" kit).
Today, for a major kit, you will need to either find a new old stock (NOS) of one of these kits from yesteryear (beware the large gaskets are probably not useable) or a major kit for your carburetor may be available from one of the custom mail-order kit manufacturers. To acquire a major kit, the identification number of your specific carburetor is required. And ALWAYS ask "what components are in the kit". That way you know what you are getting. If the vendor refuses to discuss the kit contents, run.
