Engine Running Behavior
If engine is down on power, difficult to
start or runs poorly at idling speed, first
check the spark plug.
If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor properly
adjusted, the cause may be in the
muffler.
Have the muffler checked for
contamination (coking) by a STIHL
dealer.
