ABSTRACT:
An adjustable fuel metering adapter for a carburetor includes a rectangular plate having an inlet surface and an opposite outlet surface. A needle valve chamber with a needle valve seat is formed within the plate and communicates with a threaded needle valve bore formed through a top edge surface of the plate. A pair of inlet ports are bored into the inlet surface of the plate, and a pair of outlet ports are bored into the outlet surface of the plate. A pair of inlet passages communicate respectively between the inlet ports and the needle valve chamber. A pair of outlet passages communicate between the needle valve chamber and the respective outlet ports. The inlet ports receive fuel from the fuel bowl of the carburetor, and the outlet ports are positioned to align with fuel supply passages of the carburetor. Rotation of a needle valve member received in the needle valve bore simultaneously controls the volume rate of fuel flow from the fuel bowl to the respective fuel outlet ports.
