I never see over about 140 to 150 psi max in any used 1.9 waterboxer engine.
I haven't checked a new one, which could be as high as 190,  but I wouldn't
expect to see over 150 on a used engine.

Subject: 1.9 Compression?

I'm looking at an 84 Westy on Saturday. The guy want $6500 for it. It looks
really clean but has 170K on the original motor. He sent me a copy of the
compression test he had done in 2007 when he bought it. It shows 140psi on
all 4 cylinders. I'm planning on having another one done when I go look at
it. What would be an acceptable number? I've heard 145-190.

Thanks,
Steve
