the air cleaner element installed. A
defective air cleaner can result in loss of
engine power and can cause excessive
wear or damage to the engine components

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
periodicany. Clean the area around the
spark plug base before removal, to prevent
dirt from entering the engine. Replace the
spark plug ifthe electrodes are pitted or
burned or ifthe 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 inches if necessary. If a new
spark plug is needed, refer to the PROD-
UCT SPECIFICATIONS on page 11 for the
proper replacement spark plug.
Before reinstalling the spark plug, coat the
threads lightly with graphite or light oil to
insure easy removal. Tighten the spark plug
