Description & Operation

To maintain optimum air-fuel ratio, the main air jet control system controls air flow into the main jets of the carburetor throats. When the vehicle is being started, or running in the power mode, the control unit energizes the main air jet solenoid valve in the air cleaner to close the extra air passage, increasing the fuel flow.
