As you might already know, there are small combustions taking place internally in the engine to convert the fuel into mechanical work. But no combustion can take place without the presence of oxygen. So, we need a mixture of both oxygen and fuel to be supplied to the engine for the combustion to take place. The carburetor is the device through which the fuel gets mixed with the oxygen and the mixture is then passed onto the combustion chamber where the mixture is burned and the energy is released. So the next question is, how do we create this mixture? We need to get the fuel to come in close contact with the oxygen in a place from which the mixture can be then pushed towards the combustion chamber due to some pressure difference. So the place at which they come in contact is the Venturi in the section diagram, the venturi is in between the choke shutter and the throttle shutter. The air enters the carburetor from the Air filter into the upper half of the carburetor and the fuel comes in from the fuel tank through the gap between the inlet needle and seat and settles in the bowl. When the engine is running, the air enters from the filter, and the fuel is sucked in from the bowl into the venturi, where they both combine and the mixture is then passed to the combustion chamber If you have some time in your hand, check this video of the carburetor working from a transparent view.

As it is passing through the emulsion tube, the fuel mixes with the air from the holes in the emulsion tube. One of the most common causes of poor performance is your carburetor. Begin by checking the air filter. The carburetor is the device through which the fuel gets mixed with the oxygen and the mixture is then passed onto the combustion chamber where the mixture is burned and the energy is released. The throttle valve will control the amount of mixture that leaves the carb and is directly related to the rpm of the engine. When the throttle valve is fully open, the rpm is high and when the throttle valve is closed, the Engine rpm is low. You should see a small amount of fuel trickling out of the end of the line, as well as the entry point. Carburetors adjust the balance of air and fuel based on a variety of factors, including how long the engine has been running, the type of terrain you are crossing, and your speed. In idle conditions, the throttle valve will be semi or fully closed, at fully closed, the mixtures are still able to form due to the presence of other small passages for the air to flow through,.
