Abstract
A control system improvement. A high speed air bleed path and a low speed air bleed path respectively bleed air into the high speed and low speed fuel circuits of a carburetor through either fuel circuit at any one time. A solenoid responsive to a control signal opens and closes the air bleed to control the quantity of air bled into the high speed and low speed circuits. The solenoid includes an isolator for isolating the high speed air bleed path from the low speed air bleed path to prevent cross flow of air from one air bleed path to the other. Cross flow of air between the paths adversely affects the degree of control over the delivery of fuel through the high speed and low speed fuel circuits.
