3-10 Inspectingywheelandkey
1. Inspect magnetic force of flywheel using flux
meter, or bridging with a screwdriver as shown.
2. If magnetic force is weak, replace flywheel as
follows.
3. Disconnect spark plug cap and remove spark
plug.
4. Install clean rope (B) in spark plug hole (C) to
stop crankshaft rotation.
NOTE: Do not use piston stopper to avoid piston
damage.
NOTE: Do not use power tool to remove nut (A).
Otherwise, piston damage may occur.
5. Remove nut (A) by rotating counterclockwise.

3-9Settingpoleshoeairgaps
1. Insert Module air gap gauge: 91004 (A) or 0.3
- 0.4 mm (0.012 - 0.016 in) thick feeler gauge be-
tween ywheel and ignition coil shoes.
2. Rotate ywheel until magnetic poles of ywheel
face ignition coil shoes.
3. Hold ignition coil against flywheel and tighten
the bolts to specied torque (Refer to “Service in-
formation 1-3 Torque limits”). After tightening bolts,
remove Module air gap gauge: 91004 (A) (or feeler
gauge).
NOTE: When air gap is too narrow, contact with
ywheel may result. When the air gap is too wide,
spark is weak.
