How to Clean Generator Carburetor? – Complete Guide

Like any metering system, the carburetor injection is located near the internal combustion engine in the alternator of the car, thus constantly interacting with fuel and hot air. Since it is a mechanical device with some moving parts, which are outside, it tends to get dirty. It can be dust, soot, dirt, or engine oil that settles both outside and inside the device.

Carburetor Review

The carburetor is a must-have power unit for the internal combustion engine of generators. The carburetor is needed to form the air-fuel mixture. If the fuel supply system is equipped with a carburetor, a fine fuel-air mixture enters the engine cylinders, which are easily ignited by a spark.

Precautions

Safety precautions must be taken before working on the carburetor – this is the first rule. Safety goggles are a must, as well as special gloves since the chemicals in the gasoline can irritate the skin. Another precaution is to have a well-lit, clean, and ventilated work area.

How it Works

The carburetor prepares a combustible mixture of air and fuel and feeds it to the engine in the necessary proportions. The construction of the simplest carburetor consists of a float chamber and a mixing chamber connected with each other.
A float regulates a constant fuel level in the first chamber. Fuel is transferred to the mixing chamber through the nozzle. As it passes through the atomizer it is broken up by the air jet and atomized and mixed with it. The result is an easily ignitable air-fuel mixture.
