Chuck... Try these numbers 7028875 & 7012797. There is basically 3 style of floats that are somewhat common (for the vintage carburetor) that I have seen. "D" shape, Round, and Tapered Rectangle (kinda rare). There is Camelback or notched (rare). Were his originals foam or brass? On this side of the border, cores are tough to find and most times you can get away with used floats. Hope this may help...MB.

The three types of 4GC floats. Top ones are the pontoon style, middle are the 'D' or 'rounded' style, bottom ones are the phenolic. Make sure you use the correct top gasket (cutout for the float or solid).

Hope this helps. -Al
