Spark Plug - Aztec EDGEWINDER Owner's Manual

SPARK PLUG

spark plug must be properly gapped and free of deposits.
Recommended Spark Plugs:
The recommended spark plug is the correct heat range for normal
engine operating temperatures.
1.) Stop the engine and make sure the machine is on a level
surface.
2.) Disconnect the spark plug cap, and remove any dirt from
around the spark plug area.
3.) Remove the spark plug with a 13/16-inch spark plug
wrench.
4.) Inspect the spark plug. Replace if damaged, baldy fouled, if
the sealing washer is in poor condition, or if the electrode is
worn.
5.) Measure the spark plug electrode gap with wire-type feeler
gauge. Correct the gap, if necessary, by carefully bending
the side electrode. The gap should be: 0.70-0.80 mm
(0.028-0.031 in).
6.) Install the spark plug carefully, by hand, to avoid cross-
threading.
7.) After the spark plug is seated, tighten with a 13/16-inch
spark plug wrench to compress the sealing washer.
8.) When installing a new spark plug, tighten 1/2 turn after the
spark plug seats to compress the washer.
9.) When reinstalling the original spark plug, tighten 1/8-1/4 turn after the spark plug.
10.) Securely attach the spark plug cap to the spark plug.
