The apertures (12) have a cross sectional area dimensioned to allow an air-fuel mixture to flow therethrough when a throttle member requires maximum power and corresponding air-fuel flow rates. The apertures (12) direct the air-fuel flow (30) through a "puddle" (27) of fuel that has accumulated in the bottom portion (28) of an outer well (18) of the carburetor (10) during the normal operation of an internal combustion engine. When maximum power is required from the engine, the increased air-fuel flow through the apertures (12) causes the fuel puddle (27) to vaporize or "mist", allowing the fuel to become a part of the air-fuel flow stream supplying the engine's cylinders (25) thereby increasing the engine's power and response while decreasing the engine's hydrocarbon emissions. | |
