SPARK TEST
Never hold the high-tension cord with wet hands
while performing this test.
Check for the following before conducting 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 (1) from the spark plug
(2).
Connect a known-good spark plug (3) to the spark plug
cap and ground the spark plug to the cylinder head
cover bolt (4).
Turn the engine stop switch to "ON" position.
Crank the engine by pulling the recoil starter and check
whether sparks jump across the electrodes.
SPARK PLUG CAP INSPECTION
Measure the resistance of the spark plug cap by
attaching one ohmmeter probe to the terminal in the
spark plug cap and the other to the high-tension cord
terminal.
RESISTANCE: 7.5 – 12.5 kΩ (20°C/68°F)
If measured resistance is out of specification, replace
the spark plug cap (page 8-3).
