ABSTRACT:
A balance vent for an internally vented float fuel bowl type carburetor in order to dampen pulse signal fluctuation to the internal vent that is created upon an excess vacuum buildup in the float bowl. The balance vent is a restricted passageway that communicates at one end with the internal vent circuitry and at its opposite end with the atmosphere external of the carburetor. The balance vent is sized so that the vacuum in the fuel bowl is bled off to the atmosphere only to a certain extent to permit an overall bowl vacuum to remain so that the characteristics of the internal bowl vent are maintained.
