Up until the late 1980s, most internal combustion engines relied upon a carburetor for properly mixing its fuel and air. Now cars use fuel injection.
The carburetor ensures that the right amount of fuel gets into the engine so that the combustion process can be successful. However, carburetors tend to build up dirt in them over time as they continue to be used.
If carburetors are not periodically cleaned, then they may prevent the proper amount of fuel from getting into the engine.
If there is not enough gas in the engine, it will greatly decrease your vehicle’s performance, cause your engine to sputter or just die in the middle of running, make it hard to start, or even flood your carburetor with fuel.
