Checking the Spark Plug
WARNING: Unintentional sparking can result in fire
or electric shock. Unintentional start-up can result in
entanglement, traumatic amputation, or laceration.
When you test for spark:
• Use an approved spark plug tester.
• DO NOT check for spark with the spark plug removed.
NOTICE: Spark plugs have different heat ranges. It is import-
ant that the correct spark plug is used, otherwise, engine
damage can occur. Replace the spark plug with the same
type or equivalent one.
Checking the Spark Plug Gap
Use a spark plug feeler gauge (A, Fig. 40) to check the gap
between the two electrodes. When the gap is correct, the
gauge will drag slightly as you pull it through the gap.
To adjust the spark plug gap, use a spark plug gauge and
gently bend the curved electrode. Make sure that you do
not touch the center electrode or the porcelain.

Install the Spark Plug
Tighten the spark plug with your fingers, and then, tighten
it with a wrench.
• 180 in-lbs, OR
• 1/2 turn when you install the original spark plug, OR
• 1/4 turn when you install a new spark plug.
