Checking the Spark Plug
Engine Running Behavior
If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor is properly
adjusted, the cause may be the muffler.
1
Have the muffler checked for
contamination (carbonization) by your
servicing dealer.
A
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.

Clean dirty spark plug.
2
Check electrode gap (A) and
readjust if necessary – see
"Specifications".
N
Use only resistor type spark plugs of
the approved range.
Rectify problems which have caused
fouling of spark plug:
Warning!
–
–
–
Too much oil in fuel mix.
Dirty air filter.
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot (1)
snugly onto spark plug terminal (2) of
the proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug boot and ignition wire con-
nector in the boot may create arcing that
could ignite combustible fumes and
cause a fire.
Unfavorable running conditions,
e.g. operating at part load.
Installing the spark plug
N
Screw home the spark plug, fit the
boot and press it down firmly.
