ADJUSTMENT
Skandic WT/SWT Only
Whenever the trigger coil or the magneto flywheel
is removed or replaced, the air-gap between the
trigger coil and the flywheel protrusion must be
checked and adjusted. The purpose of this adjust-
ment is to obtain the minimum clearance between
these parts — without touching at any RPM — so
that the trigger coil produces its proper electrical
output. Ignition timing must also be checked. Re-
fer to IGNITION SYSTEM.
Proceed as follows:
1. Rotate flywheel so that one protrusion aligns
with trigger coil.
2. Using a feeler gauge of 0.45 mm (.018 in) to
0.55 mm (.022 in) thick, check air-gap between
center pole of trigger coil and flywheel protru-
sion.
NOTE: A non-ferrous feeler gauge, such as a stain-
less steel one, would be useful because it will not
be attracted by flywheel magnets.
3. If necessary, adjust by slackening retaining
screws and moving trigger coil toward or away
of protrusion.
4. Retighten screws and recheck air-gap.
