PERFORMANCE ORDER
1. On models of engines with 16 valves for access to spark plugs it is necessary to remove preliminary a casing located on the centre of a head of the block of cylinders. For casing removal to unscrew eight bolts (are specified by arrows), marking position of electroconducting and keeping brackets.
2. On models with working volume 1998 sm3 with 16 valves to move apart high-voltage wires from spark plugs.
3. Before removal of stoppers of high-voltage wires from spark plugs to remove a dirt, using a pure brush, a vacuum cleaner or compressed air to prevent dirt hit in engine cylinders.
4. Check of spark plugs shows an engine condition. If the nasal part of an insulator of a spark plug pure and white, it shows that a mix too poor or "hot" spark plugs are used. If the tip and a nasal part of an insulator are covered by firm black touch, it shows that a mix too rich. If black and oil, possibly, the engine is worn out. If the nasal part of an insulator is covered by easy light brown touch the mix is optimum, and, possibly, the engine in a good condition.
5. To measure interelectrode a backlash of a candle by an edge щупа. The interelectrode backlash of a spark plug has great value as at too big or too small backlash the size of a spark of ignition and efficiency will be insufficient for normal work of the engine.
6. For installation of an interelectrode backlash to turn in an external electrode before reception of a demanded backlash. Not to bend at all the central electrode as it can split an insulator.
7. To connect high-voltage wires in strictly certain order.
