Spark plug (Fig. 20)
.024˝
(0.6 mm)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting.
○ A dirty air fi lter.
○ Hard running conditions (such as cold weather).
○ Too much engine oil
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 .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.
Gear case (Fig. 21)
Check gear case or angle gear for grease level
about every 50 hours of operation by removing the
grease fi ller plug on the side of gear case.
If no grease can be seen on the fl anks of the
gears, fi ll the gear case with quality lithium based
multipurpose grease up to 3/4. Do not completely fi ll
the gear case.

in half as shown in picture.
Hook the U-shaped end of the nylon line into the
groove (16) on the center partition of the reel.
