What is a Carburetor and How Does It Work?

A carburetor is a mechanical device that mixes fuel and air in the proper ratio to supply the engine with the required combustible mixture. In simple terms, it atomizes fuel into tiny droplets and combines it with air to create a combustible mixture that powers the engine. The carburetor consists of several components such as the float bowl, throttle valve, choke, and idle circuit that work together to regulate the fuel and air mixture.

The Structure of Honda GCV190 Carburetor

The Honda GCV190 carburetor has a simple structure that comprises the following parts: 1. Float bowl: This is the reservoir that stores fuel for the carburetor. 2. Throttle valve: It regulates the airflow into the engine by opening and closing the valve. 3. Choke: It enriches the air-fuel mixture by restricting the airflow during cold starts. 4. Idle circuit: It controls the engine's idle speed by regulating the fuel flow. 5. Main jet: It controls the fuel flow rate at high engine speeds. 6. Pilot jet: It controls the fuel flow rate at low engine speeds.
