ABSTRACT:
A carburetor is disclosed as being formed by die casting and in the process employing two opposed juxtaposed casting cores to form the induction passage and main venturi therein with the result that a flashing of die cast metal occurs as between the opposed juxtaposed cores generally transversely of the induction passage generally at the location of the throat of the venturi; after casting the carturetor, the carburetor is placed onto fixture means and a cutting and forming punch or tool is moved relative to the carburetor as to both cut through the said flashing and also seat against the metal of the upstream portion of the venturi in order to assure uniformity of contour thereof especially with respect to the venturi throat as cut and sized by the tool.
