9-5 CARBURETOR
(1)Float System
The float chamber is located directly under the carburetor. The float and the needle valves maintain a constant fuel level inside the float chamber while the engine is running.
The fuel in the tank flows into the float chamber through the needle valve. When a certain quantity of the fuel enters the chamber the float rises and when the buoyancy of the valve balances with the
(2)Pilot System
The system controls the fuel supply for engine speeds ranging from idling to
(3)Main System
The system supplies fuel for medium and high speed operations. The fuel is measured in the main jet, and then flows into the main nozzle. Air measured in the main air jet mixes with the fuel from the bleed hole of the main nozzle bursting into the main bore in the form of gas mist. Then it is again mixed with air inducted through the air cleaner to get appropriate density, and finally it is supplied to the engine.
(4)Choke System
The choke system helps start the engine in cold weather.
When the choke is closed and the engine is started, the load to the main nozzle increases and inducts a large quantity of fuel, thus facilitating starting.
