Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect for
damage or carbon blockage. If replacement parts are required,
make sure to use only original equipment replacement parts.

generator including overhead.
• It is a violation of California Public Resource Code, Section
4442, to use or operate the engine on any forest-covered,

Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a Briggs & Stratton
authorized dealer clean the cooling system (J) per
recommended intervals (see Maintenance Schedule in the

engine free from debris. Also see Cleaning.

The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve. Top speed has been
set at the factory. If adjustment is required, see a Briggs &
Stratton authorized dealer.
