11.5.2 Checking or changing the spark plug
ELIET recommends the following makes of spark plug.
B&S Vanguard - 9 pk
Honda GX 270 - 9 pk
Switch OFF the engine and pull the cable off the
•
spark plug.
Clean the area around the spark plug and
•
remove it from the cylinder head.
Using feeler gauges, check whether the distance
•
between the electrodes is 0.8 mm.
If the spark plug has suffered too much corrosion
•
or contamination, it should be replaced.
•
To check the quality of the ignition, proceed as follows :
1. Refit spark plug cap onto spark plug.
2. Hold the rubber part of the spark plug cap and press the outer electrode
against the frame of the engine.
3. Pull the starter cord.
4. Check the sparks between the electrodes.
5. If the sparks are bright and located exactly between the centres of the
electrodes, then the spark plug is still OK.
6. If the sparks are weak, irregular and not located exactly between the centres of
the electrodes, then the spark plug must be renewed.
Caution:
Refitting an old or replacing a new spark plug should be performed with the
greatest care in order to avoid damaging the screw thread in the motor.
Torque the spark plug to 20 Nm.
