Check the Spark Plugs

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
important that the correct spark plug is used, otherwise,
engine damage can occur. Replace the spark plug with the
same type or equivalent one.
Clean the Spark Plugs
Clean the spark plugs with a wire brush and sturdy knife. DO
NOT use abrasives.
Check the Spark Plug Gap
Use a spark plug feeler gauge (A, Figure 16) 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.
