SPARK PLUG
For best results, replace the spark plug every 100 hours of use. Use only the recommended spark
plug which is the correct heat range for normal engine operating temperatures. To find actual
types of recommended spark plugs please contact an authorized service center.
CAUTION! A If the engine has been running, the muffler and the spark plug will
be very hot. Be carefull not to touch this parts.
Note: I
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug must be properly gapped and free of deposits.
1. Disconnect the cap (fig. 27A) from the spark plug and remove any dirt from the spark plug
area.
2. Use the proper size spark plug wrench (fig. 28) to remove the spark plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the sealing washer is in poor
condition, or if the electrode is worn.
4. Measure the electrode gap with a suitable gauge (fig. 29). The correct gap is listed in
the Specifications. If adjustment is needed, correct the gap by carefully bending the side
electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug is seated, tighten with the proper size spark plug wrench to compress
the washer.
7. When installing a new spark plug, tighten by 1/2 turn after the spark plug seats to compress
the washer.
8. When reinstalling the original spark plug, tighten by 1/8 - 1/4 turn after the spark plug seats
to compress the washer.
9. Attach the spark plug cap to the spark plug.
Note: I
A loose spark plug can become very hot and can damage the engine. Over tightening
the spark plug can damage the threads in the cylinder head.

• Remove accumulated debris from muffler area and cylinder area.
• Make sure the muffler is without cracks, corrosion or other damage.
• If the exhaust is fitted with a spark arrester, it is necessary to keep it clean and passable.
After removing the spark arrester and scratching the rough dirt, clean the spark arrester with
a soft brush (eg. dental) from the deposits.
CARBON SEDIMENTS
