Carburetor

If you think your carburetor needs adjusting, see your
nearest Sears service center. Engine performance
may be affected at attitudes above 3,000-7,000 feet.
For operation at higher elevations, contact your
nearest Sears service center.
Spark Arrester Service
Your engine is not factory-equipped with a spark
arrester. In some areas, it is illegal to operate an
engine without a spark arrester. Check local laws and
regulations. A spark arrester is available from your
nearest Sears service center. If you need to order a
spark arrester, please call 1-800-366-PART.
The spark arrester must be serviced every 50 hours to
keep it functioning as designed.
If the engine has been running, the muffler will be very
hot. Allow the muffler to cool before servicing the
spark arrester.
• Remove spark arrester screen for cleaning and
inspection.
• Replace if screen is damaged.
