clean it and check the electrode gap. Readjust if
necessary. The correct gap is .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.
