SLOW SYSTEM
This system supplies fuel during engine operation with throttle valve closed or slight opened.
The fuel from float chamber is metered by pilot jet where it mixes with air coming in through pilot air
jet. This mixture, rich with fuel, then goes up through pilot pipe to pilot screw. A part of the mixture is
discharged into the main bore out of bypass ports. The remainder is then metered by pilot screw and
sprayed out into the main bore through pilot outlet.
