A carburetor having a plurality of orifices at different locations adjacent to the sidewall of the airflow passage therethrough and connecting passages communicating the orifices with a fuel source, such that different airflow conditions through the airflow passageway will generate different negative pressure conditions in the respective orifices and connecting passages, such that fuel will be drawn to the airflow passageway through the orifice or orifices and connected passage or passages with the greatest negative pressure conditions therein, a primary operational result being fuel delivery capable of rapidly changing corresponding to rapidly changing airflow conditions in the airflow passageway corresponding to changing operating conditions.
A method for forming at least one secondary fuel delivery circuit in a carburetor having a primary fuel delivery circuit including a primary fuel delivery passage extending through a body portion of the carburetor from an interface surface located to be disposed between the body portion and a fuel metering block removably mountable thereto to a primary fuel delivery orifice in communication with an air flow passageway extending through the carburetor, comprising the following step:
