CAUTION: Never run the engine without
the air deaner element installed. A
defective air deaner can result in loss of
engine power and can cause excessive
wear or damage to the engine components
if dirt or dust is permitted to enter the
engine through the carburetor. A damaged
air cleaner, or one that is clogged with dust
or dirt should be replaced immediately.
SPARK PLUG
Clean the spark plug and reset the gap
periodically. Clean the area around the
spark plug base before removal, to prevent
dirt from entering the engine. Replace the
spark plug if the electrodes are pitted or
burned or K the porcelain is cracked. Clean
the spark plug by carefully scraping the
electrodes (do not sand blast or use a wire
brush). Be sure the spark plug is clean and
free of foreign material. Check the elec­
trodes gap with a wire feeler gauge and
reset to .030 in. if necessary. If a new spark
plug is needed, refer to the PRODUCT
SPECIRCATtONS on page 11 for the
proper replacement spark plug.
Before reinstalling the spark plug, coal the
threads lightly with graphite or tight oil to
insure easy removal. Tighten the spark jiMug
firmly into the engine. If a torque wrench is
available, torque the spark plug to 15 foot­
pounds.
