CHECK/ADJUSTMENT
Remove the fan cover (page 5-2).
Insert the feeler gauge [1] of proper thickness between
the ignition coil [2] and the flywheel [3].
• Avoid the magnet part of the flywheel when
adjusting.
• Adjust the ignition coil air gap equally on both sides.
If measured clearance is out of specification, adjust the
air gap.
Loosen the two bolts (6 x 25 mm) [4].
Insert the feeler gauge of proper thickness between the
ignition coil and flywheel.
Push the ignition coil firmly against the flywheel and
tighten the ignition coil bolts securely.
Remove the feeler gauge.
SPARK TEST
Check for the following before conducting the spark
test.
• Faulty spark plug
• Loose spark plug cap
• Water in the spark plug cap (leaking the ignition coil
secondary voltage)
• Loose ignition coil connector
Disconnect the spark plug cap [1] from the spark plug
[2].
Connect a known-good spark plug [3] to the spark plug
cap and ground the spark plug to the cylinder head
cover bolt [4].
Turn the engine stop switch to "ON" position.
Crank the engine by pulling the recoil starter and check
whether sparks jump across the electrodes.
