THE GENERAL DATA

Normal work of the engine in the big degree depends on a condition of spark plugs.

PERFORMANCE ORDER

1. Having turned out candles, examine them.

2. If the insulator of the central electrode of a candle is covered by a deposit of light brown or grey-steel colour, the carburettor means is adjusted correctly and the candle works normally.

3. Light grey or white colour of pollution of an insulator says that a mix very poor, a black deposit on a candle – a mix reenriched.

4. If electrodes and a candle insulator are made oily, it means that or the candle gives a spark with faults, or piston rings are worn out.

5. Candles before installation need to be cleared a metal brush, to wash out gasoline and to dry.

6. To adjust a backlash between candle electrodes, turning in a lateral electrode. To bend the central electrode it is impossible. To tighten candles it is necessary the moment 20 Н·м (2,0 кгс·м).
