How Carburetors Work
The carburetor is a pipe above the engine cylinders with an air pipe and a fuel pipe connected to it.
The air pipe brings in outside air, first through an air filter to remove dirt and other debris, and then to the carburetor.
The carburetor, also known as the carb, has two valves that perfect the air to fuel ratio.
The first valve, known as the choke, regulates air flow into the carburetor to mix with the fuel and is only used when the engine is cold.
The second valve opens and closes when you depress the gas pedal and regulates how much of the combination exits the carb and goes into the engine.
As the valve opens it draws air by the venturis and pulls fuel in to mix with the air. Fuel is provided via a small fuel tank called the float-feed chamber or float bowl. As fuel in this tank decreases, the float falls, which opens a valve at the fuel inlet pipe to refill or maintain the fuel level in the tank.
