Difference between each cylinder:
68 kPa (0.7 kgf/cm2, 9.8 psi) or less
HINT
If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the spark plug hole and inspect it again.
* If adding oil increases the compression pressure, the piston rings and/or cylinder bore may be worn or damaged.
* If the pressure stays low, the valve may be stuck or seated improperly, or there may be leakage from the gasket.
NOTICE:
* Use a fully-charged battery so the engine speed can be increased to 250 rpm or more.
* Inspect the other cylinders in the same way.
* Measure the compression in as short a time as possible.
