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.
