Fuel Delivery and Air Induction: Description and Operation

Fuel metering is accomplished through carburetion. The carburetor is a downdraft fuel and air metering device having two stages of operation. The primary side has a relatively small bore, double venturis and a bridge nozzle. Primary fuel metering is accomplished with a mixture control solenoid. The secondary side of the carburetor has one large bore and a secondary main metering system, which supplies fuel to the engine during heavy load conditions.
