Compression Check: Specifications
^
Compression Ratio ............................................................................................................................................................................................. 10.9:1
The minimum compression in any one cylinder should not be less than 70 percent of the highest cylinder. No cylinder should read less than 690 kPa
(100 psi). For example, if the highest pressure in any one cylinder is 1,035 kPa (150 psi), the lowest allowable pressure for any other cylinder would
be 725 kPa (105 psi). (1 035 x 70% = 725) (150 x 70% = 105).
