ABSTRACT:
A fuel control apparatus for controlling the flow amount of fuel delivered from a carburetor having a power circuit is disclosed, in which the fuel passage of the power circuit permits the fuel in a float chamber of the carburetor from flowing toward the fuel nozzles of the carburetor in response to the reduction in the vacuum led into a vacuum chamber of the carburetor from a vacuum reservation tank in which the vacuum introduced from an intake manifold of a gasoline engine is reserved. The vacuum reservation tank has a considerable volumetric space therein defined by a sealed housing, and is disposed to the exterior of the carburetor. The fuel control apparatus also comprises a means for causing reduction in the vacuum developing in a vacuum region between the vacuum reservation tank and the vacuum chamber of the carburetor.
