IGNITION COIL (WITH BUILT-IN POWER
TRANSISTOR) CHECK
M1163001200324
Check by the following procedure, and replace if
there is a malfunction.
SECONDARY COIL RESISTANCE CHECK
Measure the resistance between the high-voltage
terminals of the ignition coil.
Standard value: 8.5 − 11.5 kΩ
PRIMARY COIL AND POWER
TRANSISTOR CONTINUITY CHECK
NOTE: .•
An analogue-type circuit tester should be used.
•Connect the negative (-) prove of the circuit tester
to terminal No. 1.
CAUTION
This test must be performed quickly (in less than
10 seconds) to prevent coil from burning and
power transistor from breakage.
RESISTIVE CORD CHECKM1163001400124
Measure the resistance of the all spark plug cables.
1. Check cap and coating for cracks.
2. Measure resistance.
Limit: Maximum 19 kΩ
SPARK PLUG CHECK AND CLEANING
<4G1>
M1163004300342
CAUTION
When pulling off the spark plug cable from the
plug always hold the cable cap, not the cable.
1. Remove the spark plug cables.
2. Remove the spark plugs.
3. Check for burned out electrode or damaged
insulator. Check for even burning.
4. Remove carbon deposits with wire brush or plug
cleaner. Remove sand from plug screw with
compressed air.
5. Use a plug gap gauge to check that the plug gap
is within the standard value range.
Standard value: 1.0 − 1.1 mm
If the plug gap is not within the standard value
range, adjust by bending the earth electrode.
CAUTION
Be careful not to allow foreign matter in
cylinders.
6. Clean the engine plug holes.
7. Install the spark plugs. 1.5 V power supply

1. Turn A/C and lights OFF. Inspect and adjust at no
load.
2. Warm engine until stabilized at idle.
3. Confirm idle speed is at standard value.
Standard value:
750 ± 50 r/min <4G1>
750 ± 100 r/min <4G6>
4. Stop engine. [ignition switch: LOCK (OFF)
position].
5. Confirm there are no sharp bends in the
accelerator cable.
6. Check the inner cable for correct slack.
Standard value: 1.0 − 2.0 mm
7. If there is too much slack or no slack, adjust play
by the following procedures.
(1) Loosen the adjusting bolts to release the
cable.
(2) Move the plate until the inner cable play is at
the standard value, and then tighten the
adjusting bolts.
(3) After adjusting, check that the throttle lever is
touching the stopper. Item Standard value
