Primary Main & Slow Air Jet Control System

Fig. 83 Primary main & slow air jet control system:

This system used on 1985-86 CRX 1500 HF federal models, Fig. 83, is designed to control air flow volume into the main and slow air jets of the carburetor depending on driving conditions and maintains optimum air/fuel ratio for achieving good fuel economy. When the solenoid valves are activated by the control unit, the primary slow and main air cut off solenoid valves supply additional air to each air passage of the carburetor allowing fuel/air mixture to lean.
