A carburetor is an older, mechanical device that mixes air and fuel for an engine by using a venturi to create a vacuum, while a throttle body is a component of a modern electronic fuel injection system that regulates the amount of air entering the engine, relying on sensors and a computer to control fuel delivery. The carburetor is a single, self-contained unit that handles both air regulation and fuel mixing, whereas the throttle body's primary job is air regulation, with fuel being delivered separately by injectors.
