ADJUSTMENT
Skandic WTSWT 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 adjustedThe purpose of this adjustment is to obtain the minimum clearance between these parts without touching at any RPM so that the trigger coil produces its proper electrical outputIgnition timing must also be checkedRefer to IGNITION SYSTEMProceed as follows: 1Rotate flywheel so that one protrusion aligns with trigger coil2Using 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 protrusionNOTE: non-ferrous feeler gauge, such as stainless steel one, would be useful because it will not be attracted by flywheel magnets3If necessary, adjust by slackening retaining screws and moving trigger coil toward or away of protrusion4Retighten screws and recheck air-gap
