The carburetor has a venturi, which is a narrow section that increases the air velocity. This increased velocity creates a low pressure area, which draws fuel from the carburetor float bowl. The fuel is then mixed with the air and sent to the engine cylinders through the intake manifold.
The carburetor has a float that controls the fuel level in the float bowl. When the fuel level drops, the float drops with it, which opens a valve that allows more fuel to flow into the float bowl. When the fuel level rises, the float rises with it, which closes the valve and stops the fuel flow.
The carburetor also has a choke, which is a butterfly valve that restricts the airflow into the carburetor. This is used to increase the fuel mixture when the engine is cold and needs more fuel to start.
Once the fuel and air mixture is created, it is sent to the engine cylinders through the intake manifold. The intake manifold is a series of pipes that connect the carburetor to the engine cylinders. The intake manifold is designed to distribute the fuel and air mixture evenly to all of the cylinders.
The fuel and air mixture is then compressed by the piston in the engine cylinder. This compression causes the fuel and air to mix together more thoroughly and become more combustible. The piston then moves down, creating a vacuum that draws the fuel and air mixture into the cylinder.
The spark plug then ignites the fuel and air mixture, causing it to explode. This explosion drives the piston down, creating power. The exhaust valve then opens, allowing the exhaust gases to escape from the cylinder.
The cycle then repeats itself, with the piston moving up and down, compressing the fuel and air mixture, and igniting it to create power.
