Carburetor Research Paper
The basic carburetor has a cylindrical hollow tube encasement called a throat or a barrel.
Inside the barrel are pistons. These pistons are solid cylinder disks that slide back and forth in the barrel. Pistons fit snugly into the barrel to allow it to move freely but are tight enough not to let air or fluid leak in the barrel.
As the pistons move downward, a partial vacuum is created inside the barrel. This partial vacuum then draws air past through the carburetor's throat and into a nozzle that sprays fuel. The mixture of air and fuel in the carburetor is then delivered into cylinders for combustion.
The amount of air pulled through partial vacuum created by the pistons is controlled by a throttle valve. The throttle valve is found at the base of the carburetor.

A venturi looks like an hour glass when it narrows down. When air rushes through the narrow ends of a venturi, the air pressure against the sides of the passage way decreases.
With this, partial vacuum is created inside the barrel. This partial vacuum then draws the fuel through the nozzle and into the air.
The pistons create partial vacuum to draw air while the venturi is responsible for drawing partial vacuum to feed fuel into the nozzle.
A float chamber or float bowl is the reservoir where fuel that enters the carburetor is stored. At the reservoir's surface, a device that floats is linked to a small valve to keep a constant amount of fuel inside the reservoir.
The carburetor also has two other nozzles are aside from the main nozzle found at the venturi of the carburetor - the idle port and the off-idle or transfer port.
The idle port, found just below the venturi, is responsible for getting fuel into the engine when there is minimal airflow in the carburetor. This happens when the engine is at a low speed.
The off-idle port, found above the idle port, feeds additional fuel to the engine during low engine
