6. Spark plugs
1). Clean off carbon deposits on the spark plug electrode using a plug
cleaner or wire brush.
2). Check electrode gap.
Adjust gap 0.6 mm to 0.7mm (0.02 and 0.03 inches)
3). Use a proper spark plug:
Recommended spark plugs: NGK B6ES (Robin EH12)
Warning! The recommended spark plug has the correct heat range for
normal engine operating temperatures. A loose spark plug can overheat
and damage the engine. Over tightening the spark plug can damage the
threads in the cylinder head.
4). Check that the spark plug washer is in
good condition. Install the spark plug
carefully,
cross-threading.
5). After the spark plug seats, tighten with a
13/16-inch spark plug wrench to compress
the sealing washer. If reinstalling the used
spark plug, tighten 1/8 - 1/4 turn after the
spark plug seats. If installing a new spark plug, tighten 1/2 turn after the
spark plug seats.
