The economizer valve is only used at wide open throttle to supply additional fuel. The accelerator pump enriches the fuel mixture with a sharp opening of the throttle, providing good acceleration of the car. Accelerator pump - diaphragm type with a mechanical drive. The manually operated choke is additionally controlled by the vacuum created in the carburetor under certain engine operating conditions.
