IGNITION COIL AIR GAP
CHECK/ADJUSTMENT
Remove the fan cover
Insert a feeler gauge [1] of the proper thickness
between the ignition coil [2] and the flywheel [3].
IGNITION COIL AIR GAP:
0.3 – 0.5 mm (0.01 – 0.02 in)
• Avoid the magnet part of the flywheel when
adjusting.
• Adjust the ignition coil air gap equally on both sides.
Pushing the ignition coil against the flywheel, tighten
the two bolts and adjust the air gap.
SPARK TEST
Check for the following before conducting the spark
test.
• Oil level
• Faulty spark plug
• Loose spark plug cap
• Water in the spark plug cap (ignition coil secondary
voltage leaking)
• Loose ignition coil connector
Disconnect the spark plug cap [1] and spark plug [2].
Attach the removed spark plug to the plug cap.
Set the engine switch to the "ON" position. Ground the
negative (-) electrode (i.e. threaded part) of the spark
plug against the recoil starter mounting nut and pull the
recoil starter to check whether sparks jump across the
electrodes.
