1. Loosen two bolts (A) and insert Module air gap
gauge: 91004 (B) or 0.3 - 0.4 mm (0.012 - 0.016
in) thick feeler gauge between fl ywheel (C) and ig-
nition coil shoes (D).
2. Rotate fl ywheel (C) until magnetic poles of fl y-
wheel face ignition coil shoes (D).
3. Hold ignition coil against fl ywheel (C) and tight-

spark is weak.
4. Reassemble all removed parts.
1. Inspect magnetic force of fl ywheel (A) using fl ux
meter, or screwdriver (B) as shown.
2. If magnetic force is weak, replace fl ywheel (A)
as follows.
