ABSTRACT:
A control system (1) for bleeding air into the high speed and low speed fuel circuits (HS and LS) of a carburetor (C) mounted on an internal combustion engine (E). The carburetor has an air passage (AP) to which fuel is delivered to mix with air and form a mixture combusted in the engine. Air is directed from an air inlet (9) through a first air flow path (5) to the high speed fuel circuit and through a second air flow path (7) to the low speed fuel circuit. An isolator (57) prevents crossover of air from one air flow path to the other. A flow control (77) opens and closes the first and second air flow paths, the flow control opening and closing both air flow paths substantially simultaneously.
