Go take the top off your toilet, and push the flush handle. Watch what the water in the tank does. The "drop" of the tank float doesn't have anything to do with how high the water rises in the tank, does it? Your carburetor float works the same way. The "float level" adjustments controls how high the gasoline rises in the carburetor, just like the toilet tank float shuts the water off when it reaches the top of its travel. You need to lower the "float level" adjustment to its correct position and be sure no dirt or debris is allowed to enter the carburtetor (good inline fuel filter)to be sure the needle valve shuts the incoming gasoline off so it can't flood the engine.
