Exhaust Emission Systems - CAPRI/CORTINA: Operation: Carburetor
1600 cc models use an Autolite 1-Bbl. while 2000 cc models use a Weber 2-Bbl. carburetor. With deceleration valve open, high manifold vacuum is sensed by deceleration section of carburetor. Vacuum draws a metered amount of fuel and air from fuel pick up tube and air bleed, which flows from outlet tube through deceleration valve and into intake manifold. This extra quantity of fuel and air, coupled with other engine modifications provides improved combustion. Deceleration section of carburetor requires no maintenance but should fuel pick up tube be damaged, upper body casting must be replaced.
