How does the carburetor diaphragm work?
A flexible diaphragm forms one side of the fuel chamber and is arranged so that as fuel is drawn out into the engine, the diaphragm is forced inward by ambient air pressure. As fuel is replenished the diaphragm moves out due to fuel pressure and a small spring, closing the needle valve.
