there is possibly a non-combustible fuel-
air mixture in the combustion chamber of
the engine that is too rich– the engine

clear and then restart the engine
N As an alternative, after engaging the
chain brake, you can push in the
decompression valve and, while
holding the unit down with one knee

several times until the engine starts
WARNING
To reduce the risk of fire and burn injury,
never pull the starter cord or attempt to
restart the engine with the spark plug or
the spark plug boot removed. In the start

starter rope will create sparks that can
ignite fuel and/or fumes.
