IGNITION SYSTEM

1. Insert Module air gap gauge: 91004 (A) or 0.3

- 0.4 mm (0.012 - 0.016 in) thick feeler gauge be-

tween ﬂ ywheel and ignition coil shoes.

2. Rotate ﬂ ywheel until magnetic poles of ﬂ ywheel

face ignition coil shoes.

3. Hold ignition coil against flywheel and tighten

the bolts to speciﬁ 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

ﬂ ywheel may result. When the air gap is too wide,

spark is weak.

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. Install Piston stopper 897537-30130 (A) into

spark plug hole by hand, to stop crankshaft rota-

tion.

NOTE: Do not use power tool to remove nut (B).

Otherwise, piston damage may occur.

4. Remove nut (B) by rotating counterclockwise.
