(c) Using a 16 mm plug wrench, remove the 4 spark plugs.
(d) Visually check the spark plug for thread damage and insu-
lator damage.
If abnormal, replace the spark plug.
Recommended spark plug:
DENSOPK20R11
NGKBKR6EP−11
(e) Inspect the electrode gaps.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE:
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip. Never attempt
to adjust the gap on the used plug.
(f) Clean the spark plugs.
If the electrode has traces of wet carbon, allow it to dry and then
clean with a spark plug cleaner.
Air pressure: Below 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or less
HINT:
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
(g) Using a 16 mm plug wrench, install the 4 spark plugs.
Torque: 18 N·m (180 kgf·cm, 13 ft·lbf)
(h) Reconnect the high−tension cords from the spark plugs.
4. INSPECT IGNITION COILS
(a) Disconnect the ignition coil connector.
(b) Disconnect the high−tension cord from ignition coil.
(c) Inspect the primary coil resistance.
Using an ohmmeter, measure the resistance between the
positive (+) and negative (−) terminals.
Primary coil resistance:
Cold0.36 − 0.55 Ω
Hot0.45 − 0.65 Ω
If the resistance is not as specified, replace the ignition coil.

DRIVE BELT
INSPECTION
INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.
(b) Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG−20 (95506−00020)
Borroughs No. BT−33−73F
Drive belt tension:
New belt: 95 − 145 lbf
Used belt: 60 − 100 lbf
If the belt tension is not as specified, adjust it.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
