Abstract
In at least some implementations, a valve for a carburetor that is moveable between open and closed positions includes a first valve portion adapted to at least substantially inhibit a first fluid flow in the carburetor when the valve is closed and a second valve portion associated with the first valve portion to at least substantially inhibit a second fluid flow in the carburetor when the valve is closed. In this way, two fluid flows may be at least substantially inhibited at the same time by the valve. In some forms, the fluid flows may include a primary fluid flow to an engine and a secondary fluid flow, such as from an accelerator pump, to the engine.
