Abstract
In a carburetor having an induction passage, a variable venturi in the induction passage, a fuel bowl and means for metering fuel flow from the fuel bowl to the induction passage, the method of compensating for changes in barometric pressure due to either atmospheric or altitude changes is disclosed as applying a vacuum or reduced pressure to the interior of the fuel bowl thereby reducing the fuel pressure which would otherwise exist, and causing a corresponding reduction in the mass rate of fuel flow in relation to the volume rate of air flow generally in accordance with a reduction in ambient pressure.
