Main Jet System

Each mixing chamber has its own separate main jet system. The main jets of both front mixing chambers are supplied by front float chamber. Main jet of rear mixing chamber is supplied by rear float chamber. Fuel flows through main jet into mixing tube cavity. Intake manifold vacuum, in mixing chamber, draws fuel out of mixing tube cavity by way of the outlet bore. This lowers fuel level in mixing tube. An equalizing air supply enters through air corrector jet and blends with refill fuel supply after passing through bores in mixing tube to form an emulsion. Air corrector jet ensures that composition of air/fuel mixture is correctly maintained in all speed ranges to suit requirements of engine.
