2. Compression
A: INSPECTION
CAUTION:
After warming-up, engine becomes very hot. Be
careful not to burn yourself during measure-
ment.
1) After warming-up the engine, turn the ignition
switch to OFF.
2) Make sure that the battery is fully charged.
3) Release the fuel pressure.

4) Remove all the spark plugs. 4, REMOVAL, Spark Plug.>
5) Check the starter motor for satisfactory perfor-
mance and operation.
6) Hold the compression gauge tightly against the
spark plug hole.
NOTE:
When using a screw-in type compression gauge,
the screw (put into cylinder head spark plug hole)
should be less than 18 mm (0.71 in) long.
7) Fully open the throttle valve.
8) Crank the engine by means of the starter motor,
and read the maximum value on the gauge when
the pointer is steady.
9) Perform at least two measurements per cylinder,
and make sure that the values are correct.
Compression (350 rpm and fully open throttle):
Standard:
1,275 — 1,471 kPa (13.0 — 1.50 kgf/cm2,
185 — 213 psi)
Service limit:
1,128 kPa (11.5 kgf/cm2, 164 psi)

3) Install the fuse of fuel pump to main fuse box.
4) Start the engine.
5) Measure the fuel pressure after warming up the
engine.
Fuel pressure:
Standard: 338 — 348 kPa (3.4 — 3.5 kgf/cm2,
49 — 50.5 psi)
NOTE:
The fuel pressure gauge registers 10 to 20 kPa (0.1
to 0.2 kgf/cm2, 1 to 3 psi) higher than standard val-
ues during high-altitude operations.
