These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting diffi culties. If the engine is low on power,
diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rst. If the spark plug is dirty,
clean it and check the electrode gap. Re-adjust
if necessary. The correct gap is 0.024˝ (0.6 mm).
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.

NOTE
In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this
machine was originally equipped with resistor
spark plug, use same type of spark plug for
replacement.
