4. Clean with plug cleaner. Sand which has accumulated in
the screw thread of the plugs is blown out by compressed
air.
5. Using the plug gap gauge, check whether the plug gap reading
is normal, and if not, adjust it.
Standard value : 1.0-1.1 mm (.039-.043 in.)
CHECKING SPARK PLUG CABLE
(1) Check that there are no cracks in the cap or in the insulating
coating.
(2) Ctieck the resistance value.

CHECKING THE IGNITION COIL
(1) Measurement of the resistance of the external resistor
Measure the resistance of the external resistor.
Standard value : 1.2-1.4 IR
(2) Measurement of the resistance of the primary coil
Measure the resistance between the positive (+) terminal
and the negative (-) terminal of the ignition coil.
Standard value : 1.1-1.3 IR
(3) Measurement of the resistance of the secondary coil
Measure the resistance between the high voltage terminal
and the positive (+) terminal of the ignition coil.
Standard value : 14.5-19.5 kfl
