Engine having carburetor with bridge circuit

A carburetor (22a) including an airflow passage (34) through which varying amounts of air flows, a variably positioned throttle valve (36) located in the airflow passage, the amount of air flowing through the airflow passage being varied in response to the position of the throttle valve, a source of stored liquid fuel, a well (48) containing liquid fuel and in independent fluid communication with the source of stored liquid fuel, a nozzle (44) extending between the liquid fuel contained in the well and the airflow passage, the nozzle having an outlet (42) located upstream of the throttle valve in the airflow passage, a variable amount of the liquid fuel contained in the well being conveyed through the nozzle to the airflow passage in response to the amount of air flowing through the airflow passage, and an idle circuit (54a) containing liquid fuel and having at least one idle fuel outlet (56, 58, 60) located in the airflow passage downstream of the throttle valve, a variable amount of the liquid fuel contained in the idle circuit being conveyed to the idle fuel outlet in response to the amount of air flowing through the airflow passage, characterized by the idle circuit being in independent fluid communication with the source of stored liquid fuel and the well. The present invention also includes, in combination with this carburetor, an internal combustion engine (20a).
