2. Mark wires of high voltage and disconnect them, using the special tool (it is specified by an arrow) if it is necessary. |
3. Clear area around spark plugs and unscrew candles. |
4. The condition of spark plugs can give valuable information on a condition of the engine. |
5. If a candle tip pure and white, without deposits, so fuel mix is too poor. |
6. If the tip of a candle is covered with black deposits, so fuel mix is too saturated. |
7. If the tip of a candle is covered with light brown or gray deposits, so fuel mix is adjusted correctly and the engine, most likely, in good shape. |
|
8. The spark gap of multielectrode spark plugs is not subject to adjustment. |
