IGNITION COIL
IGNITION COIL INSTALLATION
Attach the ignition coil (1) and loosely tighten the two
6 x 28 mm flange bolts (2).
Insert the thickness gauge (3) of proper thickness
between the ignition coil and the flywheel.
Adjust the ignition coil air gap equally on both sides.
Push the ignition coil firmly against the flywheel and
tighten the 6 x 28 mm flange bolts securely.
Remove the thickness gauge.
SPARK TEST
Inspect the following before performing the spark test.
• Faulty spark plug
• Loose spark plug cap
• Water in the spark plug cap (Leaking the ignition coil
secondary voltage)
• Loose ignition coil connector.
Disconnect the spark plug cap from the spark plug.
Remove the spark plug and reattach the spark plug
cap.
Ground the spark plug to the cylinder head.
Crank the engine by pulling the recoil starter forcefully
and check whether sparks jump across the electrode.
If there is no spark, replace the spark plug with a known
good one and retest.
SPARK PLUG CAP INSPECTION
Remove the spark plug cap from the high tension cord.
Attach the tester probes to the terminal connected to
the spark plug and terminal connected to the high
tension cord of the spark plug cap.
There should be a continuity between the terminals.
If there is no continuity, replace the spark plug cap.
