7. Fully depress the accelerator pedal and crank the engine for 5 to 10 seconds.
8. Record the compression of the three combustion chambers and cranking speed.
Compression:
589 kPa (6.0 kgf/cm2, 85 psi)-250 rpm.
Differential limit between chambers:
147 kPa (1.5 kgf/cm2, 21 psi)-250 rpm.
9. Check the rear chambers by using the same procedure.
10. Compensate the compression values if they are measured at cranking speeds other than standard or if they are measured at high altitude.
Cranking speed compensation
Compensate the compression according to the cranking speed.
Altitude compensation
Compensate the compression according to the altitude.
