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 the muffler.
Have the muffler checked by a servicing
dealer for contamination
(carbonization).
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
