Zusammenfassung:	A carburetor with a fuel and air mixing passage and a fuel delivery system may include a valve actuated by a diaphragm with no penetrations through at least the portion of the diaphragm exposed to a fuel metering chamber. The diaphragm may include at least two convolutions increasing a surface area of the portion of the diaphragm exposed to the fuel metering chamber relative to the surface area of a plane exposed to and covering the fuel metering chamber. A diaphragm may be in the form of a bellows with at least two convolutions. The diaphragm may be made of a suitable polymer or one or more pieces of a thin metal sheet or foil.
