A carburetor has two purposes:
- It controls the fuel. There is a little screw, and if you turn it in, it allows more fuel into the engine itself. There is also a small jet that sprays the fuel into the air, and the engine sucks it up.
- It controls the mix of air and fuel to achieve the desired burning conditions in the engine
