Control of spark plugs

Visual inspection of the working part of spark plugs can reveal the condition of the engine.

If the nose of the insulator is covered by black touch, it indicates that the mixture is too rich. If plaque is black and oily it testifies to deterioration of the motor and the need to check and repair. If the nose of the insulator is covered by light brown touch the mix structure is optimum also the engine is in good condition.

If the 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 so, it is necessary to adjust the composition of the fuel mixture or replace the spark.
