This brand-new plastic float fits the Weber 32/36 DGV (including 5A), DGAV, DGEV, DFAV, DFEV, and 38 DGAS carburetors. Float height is critical to the proper operation of Weber progressive carburetors. A broken float can cause the fuel level to rise too high, causing the car to run rich.
Weber recommends setting the height of a plastic float at 35mm from the bottom of the float to the bottom of the carb top plate, with the plate held vertically and the float hanging downwards, making light contact with the needle valve. (Racing engine builders often recommend adjusting this height to 33mm for a richer mixture in FF1600 racing.)
Weber no longer makes a brass float for the 32/36 DGV carburetor.
