Vacuum-operated fuel valve
The valve diaphragm is supported by a spring and normally blocks fuel flow. During the intake stroke, vacuum in the intake manifold travels through a hose to the valve. Under atmospheric pressure, the diaphragm bends and fuel flows by gravity into the carburetor.

If the carburetor float chamber is empty, the float is down, allowing fuel in. As the chamber fills, the float rises and pushes the needle valve upward. Once the correct level is reached, the needle blocks further fuel supply.
