Spark plug (Fig. 36)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting.
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter.
○ Hard running conditions (such as cold weather).
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. Readjust 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.
