One of the most important "enemies" of the carburetor is poor-quality fuel, which is very much at gas stations in Russia. The use of such fuel will lead to various kinds of failures in the carburetor, and this in turn will lead to a significant reduction in the service life of the VAZ 2108 carburetor.
Currently there are helpers who can avoid this situation, for example, a gas analyzer. It measures the level of various gases: oxygen, carbon monoxide and hydrocarbons. But its application is not always possible. In addition, candles, or rather their condition, also help to learn about the concentration of substances.
If at the tip of the candle there is a snuff of gray-brown color, this means that the mixture is made in the correct proportion. Nagar of black color means that the fuel prevails, and white - an excess of air. Sometimes a visual inspection of the carburetor also helps. Dirt, rust, carbon on the surface of the carburetor - a bad sign.
