A while back I asked in a post about ideas regarding the poor idling of my 300C. I have come a long way since then. I have discovered that there are a few cracks in the primary side of the front carburetor (2534S) around the pump well area at the bottom of the bump-out that houses the accelerator pump. I know the cracks have been there a while because, during a rebuild, the entire primary was closed off to avoid a gas leak. That would definitely affect the idle. The cracks are confined to what the book calls “the main body”, which is the middle of the three sections that make up the carburetor. The 1957 300 Service Bulletin shows that “The four-barrel carburetors are of the same basic design as those used on the C-76 Models” which is the New Yorker (2590S). The parts book shows that the 1957 Imperial and the 1958 New Yorker also interchange (2590S and 2448S).
Does anyone have a cannibalized or otherwise mangled carburetor from a 1957 or 58 New Yorker or Imperial that they would be willing to sell? The grungier the better because I only need one part: the middle section or main body of the carb.
Visually, there appear to be other differences between the 2590S and the 2534S that the Service Bulletin does not mention, but I will deal with those as they come.
OR….Does anyone know of a gasoline-resistant material that I can safely use to patch my poor WCFB 2534S?
Does anyone know of a different auto manufacturer that used a similar WCFB carburetor that interchanges with the 2590S/2534S. Corvette, for instance?
