The carburetor is located between the engine's intake pipe and the air filter. Function of the carburetor: The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the engine's operation. Components of the carburetor: The carburetor includes a starting device, idle device, medium load device, full load device, and acceleration device. Depending on the engine's different working state requirements, the carburetor automatically adjusts the corresponding concentration and outputs the appropriate amount of mixed gas. To ensure the mixed gas is uniformly blended, the carburetor also has the effect of atomizing the fuel for the machine's normal operation.

I've been fixing cars for over 30 years and often encounter this issue. In older car models, the carburetor is usually installed near the intake pipe on top of the engine, right below the air filter box. You can easily spot it by opening the hood—it's a metal or plastic component connected to several small tubes and wires. Why locate it? Because it's responsible for mixing air and fuel. If it's improperly positioned or leaking, the car may have difficulty starting, emit black smoke, or even experience a surge in fuel consumption. On older Chevrolets or Toyotas, its position is particularly obvious, but modern cars have long switched to electronic fuel injection systems, which are much more hassle-free. Regularly checking the carburetor is crucial—cleaning carbon deposits or adjusting the air-fuel mixture can prevent breakdowns on the road, which is a major safety concern.

I drive classic cars, those Ford and GM models from the 70s and 80s where the carburetor sits right under the hood in the most visible spot, just below the air cleaner. Pop the hood and you'll see it immediately—looks like a box with tubes. During daily driving, this thing easily gets clogged with dust, causing hard cold starts. My advice is to locate the air cleaner first after opening the hood—the carburetor connects right beneath it. Check the fuel lines and whether the mounting bolts are loose. If it's severely worn out, you'll need a full replacement, otherwise the car won't run smoothly.

The carburetor is primarily installed on the engine's intake pipe, specifically positioned below the air filter and directly connected to the intake manifold. Its function is to mix air and gasoline to form a combustible gas for engine combustion. In older vehicles, it is typically secured with screws in the central upper area of the engine and resembles a metal box in appearance.
