The analysis of spark plugs

The visual control of a working part of spark plugs can show an engine condition.

If the nasal part of an insulator is covered by black touch, it means that a mix too rich. If a touch black and oily it testifies to deterioration of the engine and necessity of its check and repair. If the nasal part of an insulator is covered by light brown touch the mix structure is optimum also the engine is in a good condition.

If a nasal part of an insulator of spark plugs pure and white, without a touch it testifies to too poor mix. It also specifies that the candle too hot, that is warmly from the central electrode is taken away slowly. If it so it is necessary to adjust structure of a fuel mix or to replace a candle.
