GENERAL INFORMATION

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

If the nasal part of an insulator is covered with a black raid, it means that a mix too rich. If the raid black and oily, it testifies to wear of the engine and need of its check and repair. If the nasal part of an insulator is covered with a light brown raid, the structure of a mix is optimum and the engine is in a good condition.

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