Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect for dam-
age or carbon blockage. If replacement parts are required,
make sure to use only original equipement replacement
parts.
NOTE: You can purchase a new spark arrester screen by
calling 1-800-4-MY-HOME (469-4663).
Clean and inspect the spark arrester as follows:
1. To remove muffler heat shield (A) from muffler (B),
remove four screws that connect guard to muffler
bracket.
2. Remove four screws that attach spark arrester screen (C).
3. Inspect screen and obtain a replacement if torn,
perforated or otherwise damaged. DO NOT use a
defective screen. If screen is not damaged, clean it with
commercial solvent.
4. Reattach screen and muffler guard.
Air Cooling System
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 Sears or other
qualified service dealer clean the cooling system per
recommended intervals (see Maintenance Schedule). Equally
important is to keep top of engine free from debris. See
Generator Cleaning.
Check Valve Clearance
Regular valve clearance check and adjustment will improve
performance and extend engine life. This procedure cannot
be done without partial engine disassembly and the use of
special tools. For this reason we recommend that you have a
Sears or other qualified service dealer check and adjust valve
clearance at recommended intervals.
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve and governed idle, if
equipped. Governed idle and top speed have been set at the
factory. If adjustment is required, see a Sears or other
qualified service dealer.
