Individual cylinder tuning booster for a carburetor

A carburetor for an internal combustion engine having at least at least two combustion cylinders, the carburetor comprising

• a body having at least one barrel formed therein defining an airflow passageway for the passage of air from outside the carburetor into the two cylinders of the internal combustion engine when the carburetor is attached to the internal combustion engine,
• a throttle valve disposed in the barrel for controlling the amount of fuel and air that is passed from the barrel to the cylinders of the internal combustion engine, the throttle valve being constructed so that air and fuel flow on opposite sides of the throttle valve, and
• a nozzle mounted on the carburetor body and extending transversely across the barrel upstream of the throttle valve, the nozzle having an airfoil shape and defining a fuel inlet configured to receive fuel, at least one fuel outlet configured to permit the fuel to flow out of the nozzle, and a fuel passage fluidly connecting the fuel inlet and the fuel outlet so that the fuel can flow from the fuel inlet to the at least one fuel outlet, the nozzle positioning the at least one fuel outlet in the airflow passageway of the barrel of the carburetor so that the fuel flows into the airflow passageway of the carburetor and mixes with air as the fuel flows through the at least one fuel outlet.

A method of tuning a carburetor to provide fuel/air mixtures to two cylinders of an internal combustion engine fed by a single barrel of the carburetor, the method comprising:

• determining that a fuel/air mixture from the carburetor to at least one of the two cylinders deviates from a standard fuel/air mixture;
• and
• installing a nozzle having an airfoil shape into the carburetor that is constructed to deliver fuel to an airflow passageway of the barrel so that the fuel/air mixture of at least one of the two cylinders is brought closer to the standard fuel/air mixture.
