Understanding the Function of a Carburetor

The carburetor is at the heart of your car’s engine. It mixes fuel and air in the right ratio for the engine. This ensures your car runs well, uses fuel efficiently, and lasts longer.

What Does a Carburetor Do?

The carburetor controls air and fuel flow into the engine. It uses jets, valves, and chambers to mix air and fuel perfectly. This mix is then ignited in the engine’s cylinders, powering your car.

Importance of Keeping It Clean

Keeping the carburetor clean is key for your engine’s health. Over time, it can get clogged with deposits and debris. This messes up the air-fuel mix, causing problems like poor power, bad fuel economy, and more.

Regular cleaning of your carburetor keeps your engine running smoothly. It boosts performance and extends your engine’s life. Make sure to clean your fuel system and carburetor often to keep your car in great shape.
