ABSTRACT:
A control system for a feedback carburetor in which a controlled vacuum is applied to the carburetor fuel bowl to reduce the fuel flow rate and provide maximum fuel economy. Engine speed is monitored and reduced a predetermined amount during steady state cruising through use of an air control solenoid to apply the controlled vacuum. The controlled vacuum is removed during acceleration or when engine speed is outside the range of steady state cruise speed.
