2. Adjustment of ignition coil air gap
1) Insert a thickness gauge or a piece of paper of the
same thickness between the ignition coil and flywheel.
2) Push the ignition coil firmly toward the flywheel by
hand and tighten the bolt.
Avoid the flywheel’s magnet when adjusting, and ensure clearances at both ends of ignition coil
are equal.
3. Inspection of ignition coil, lighting coil and charging
coil
1) Ignition coil
< Primary side >
Measure the resistance of primary coil by attaching one
ohm-meter lead to the ignition coil’s primary lead while
touching the other test lead to the iron core.
Primary side resistance
0.8~1.0Ω
< Secondary side >
Measure the resistance of the secondary side of the coil
by removing the spark plug cap and touching one test
lead to the high tension cord while touching the other test
lead to the iron core.
Secondary side resistance
