INSPECTION
1. Check that the battery is fully charged. Recharge it if neces-
sary. (Refer to Section G.)
2. Warm up the engine to normal operating temperature.
3. Turn the engine OFF.
4. Remove all spark plugs.
5, Disconnect the ignition coil connector.
6. Connect a compression gauge to the No.1 spark plug hole.
7. Fully depress the accelerator pedal and crank the engine.
8. Record the maximum gauge reading.
9. Check each cylinder.
Compression:
1,256 kPa (12.6 kg/cm’, 182 psi)-300 rpm
Minimum:
883 kPa (9.0 kg/cm2, 128 psi)-300 rpm
Max. difference between cylinders:
196 kPa (2.0 kg/cm2, 28 psi)
10. If the compression in one or more cylinders is low, pour a
small amount of engine oil into the cylinder and recheck
the compression.
(1) If the compression increases, the piston, piston rings,
or cylinder wall may be worn.
(2) If the compression stays low, the valve may be stuck
or seating improperly.
(3) If the compression in adjacent cylinders stays low, the
cylinder head gasket may be defective or the cylinder
head distorted.
Il. Connect the ignition coil connector.
12. Install the spark plugs.
