What does a carburetor do?

A carburetor is a device in many gasoline engines that mixes air and fuel in the right proportion before sending it into the engine’s cylinders.

What does a carburetor do?

Here’s the simple idea:

Engines need a precise mix of air + fuel to run properly.
The carburetor pulls in air, then uses that airflow to draw in gasoline.
It blends them into a fine mist so the mixture can ignite efficiently when the spark plug fires.

Think of it like a mechanical “fuel chef”—it measures and mixes the ingredients so combustion can happen smoothly.

What it controls

A carburetor adjusts the mixture based on:

Throttle position (how much you press the gas pedal)
Engine speed
Temperature (cold starts need more fuel)
Why you don’t see them much anymore

Most modern vehicles use fuel injection systems instead of carburetors because they’re:

More precise
More fuel-efficient
Better for emissions

Carburetors are still common in:

Older cars (pre-1990s, roughly)
Small engines (like lawnmowers, chainsaws, motorcycles, snow blowers, generators and more)
