b.Adjustment of clearance between ignition coils
When re-assembling the ignition coil, adjust the clearance
between ignition coil and flywheel.
1) Slightly screw the mounting bolt of ignition coil.
2) As shown in the figure, insert the thickness gauge into
the clearance of ignition coil and flywheel, or
Insert the paper of the same thickness on the circle of
the flywheel.
3) Press the ignition coil on the flywheel with hand and
4) fasten these two bolts.
Note
a) Adjust two ends of the ignition coil to the same clearance.
b) Avoid magnet steel of flywheel when adjusting.
Check
Ignition coil:
<Resistance value at the primary side>
Connect the tester terminal with the conductor terminal and
coil iron core to measure the resistance value at the primary side.
Resistance value at the
primary side
1.0-1.4 Ω
<Resistance value at the secondary side>
Connect the tester terminal with the high-voltage wire with the
spark plug cap removed and the coil iron core to measure the
resistance value at the secondary side.
Resistance value at the
secondary side
6.2-7.6 KΩ
Note
Not removing the spark plug cap during measurement will cause false readings.
