Carburetor suitable for WT286 021 023 025 ms210 ms230 ms250 chainsaw. A carburetor is a fuel supply system for an internal combustion engine, commonly used in equipment such as chainsaws. It functions by mixing liquid fuel, typically gasoline, with air to create a combustible mixture for engine combustion. Key components of a carburetor include: - Intake pipe: allows air to enter the carburetor. - Throttle valve: controls airflow to regulate engine speed and power output. - Nozzle: delivers and atomizes fuel, mixing it with incoming air. - Float chamber: stores fuel and maintains a consistent fuel level for steady supply. - Mixing chamber: where fuel and air combine to form a combustible mixture. - Fuel pump: in certain models, helps maintain proper fuel pressure for reliable engine performance. The carburetor operates by drawing air through the intake pipe and throttle valve into the mixing chamber. Fuel is released from the float chamber through the nozzle and atomized into the airflow. The fuel and air mix in the mixing chamber to form a combustible mixture, which then travels through the intake pipe into the engine cylinder. There, it is compressed, ignited, and burned to produce power.
