SPARK PLUG
• A worn or fouled spark plug can cause a loss of power,
difficulty starting or rough idle (Figure 5).
• If the spark plug is dirty, clean it with a wire brush and check
the electrode gap. Readjust if necessary. The correct gap is
.020” (0.50 mm).
• The spark plug should be replaced after 40 hours of operation
or earlier if the electrode is badly corroded.
• Always use the recommended spark plug type. Using the
wrong spark plug can severely damage the piston and cylinder
(see page 9 for part #).
Figure 5
CARBURETOR
• The function of the carburetor is to mix fuel with air.
Adjustments other than idle speed should be made by a
servicing dealer.
•
Before adjusting the engine idle speed, make sure the air
filter is clean and the engine is warmed up.
T – Idle Screw
is adjusted so that the engine idles smoothly
but the clutch does not engage (Figure 6).

If saw has been running satisfactorily and there is a gradual decrease in power and
drop in RPM at full throttle, the filter may have become dirty or saturated with water.
