) and
remove cover.
2. Remove fastener (
C
), washer (
D
), and foam
element (
E
).
3. Remove support cup (

) from foam element.
4. Wash foam element in liquid detergent and water.
Squeeze dry foam element in a clean cloth.
5. Saturate foam element with clean engine oil. To
remove excess engine oil, squeeze foam element
in a clean cloth.

Inspect Muffler and Spark Arrester
The engine exhaust muffler has a spark arrester

or other damage. Inspect spark arrester screen for
damage or carbon blockage. Clean if carbon blockage
is found or replace if damaged. If replacement parts
are required, make sure to use only original equipment
replacement parts.

fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you
have a Briggs & Stratton authorized dealer clean the
