To reduce the risk of fire and burn
injury, use only spark plugs
authorized by STIHL. Always press
spark plug boot (2) snugly onto
terminal (1) 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 connector in the boot
may create arcing that could ignite
combustible fumes and cause a fire.

Engine Running Behavior

If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor and throttle
cable are properly adjusted, the cause
may be in the muffler.
Have your STIHL dealer inspect the
muffler for carbonization.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers.
