Spark plug (Fig. 31)
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. 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.
0.024"(0.6 mm)
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.
Muffl er (Fig. 32)
Remove the muffl er and clean out any excess carbon
from the exhaust port or muffl er inlet every 100 hours
of operation.

Cylinder (Engine cooling) (Fig. 33)
The engine is air cooled and air must circulate freely
around engine and over cooling fi ns on cylinder head
to prevent overheating.
Every 100 operating hours, or once a year (more often
if conditions require) clean fi ns and external surfaces of
engine of dust, dirt and oil deposits which can contribute
to improper cooling.
NOTE
Do not operate engine with engine shroud or muffl er
guard removed as this will cause overheating and
engine damage.
Oiler port (Fig. 34)
Clean the chain oiler port (33) whenever possible.
Guide bar (Fig. 35)
Before using the machine, clean the groove and oiler
port (34) in the bar with the special gauge off ered as an
optional accessory.
