compression on a w-58

[Rock Richardson]

recently did a compression test on my w-58 and got 300 psi. is that low for these engines ?
thanks Rock

From the owner’s manual:

Check compression pressure

Remove each glow plug and check cylinders, one by one, using a compression pressure gauge. If the pressure differs by more than 3.0 kg/cm2(42.7 psi) between cylinders or if the cylinder pressure is less than 30 kg/cm2 (427.0 psi) at 200 RPM, correct it.

Was there a big difference between cylinders?
