Carburetor Valve Float at Pamela Burke blog

Carburetor Valve Float. The fuel inlet to a carburetor is slightly more complex than we've described it so far. As the chamber feeds fuel to the carburetor, the fuel level sinks, and the float falls with it. The float circuit includes the float (brass, or nitrophyl), needle & seat, or float valve, bowl vent & float bowl. The float level and float drop should be measured to insure you get proper fuel amounts. The float valve is a fantastically simple mechanism to regulate fuel needs for the carburetor. A float that is too high will allow too much fuel into the float bowl and the engine will run too rich. Unfortunately, it is often problematic when fuel is left in the carburetor for an extended. Because the carburetor can’t use fuel under pressure, whether delivered by a fuel pump or gravity, the float chamber is kept at atmospheric pressure. Its primary function is to regulate the fuel level within the carburetor. Carburetors work on the venturi effect, which says that pressure decreases and velocity increases as a fluid is forced to go through a constriction. As fuel is consumed, the float descends, opening the inlet valve to allow more fuel into the chamber.
