Note: When removing the high-voltage wire, pull on the cap, not on the wire, in order to avoid damage to the latter.
2. Using a spark plug wrench, remove all spark plugs from the cylinder head.
Note: Be careful not to let dirt get into the cylinders through the open spark plug holes.
3. Check spark plugs for defects.
4. Using a special probe, measure the gap between the spark plug electrodes and adjust if necessary.
Rated value:
- For candles designed for unleaded gasoline - 1.0-1.1 mm
- For candles designed for leaded gasoline - 0.7-0.8 mm
5. Insert the candle into place and tighten to the required torque (20-30 Nm).
6. Engine condition can be judged by deposits around the spark plug electrodes.
