Here is a link to a service manual for that engine. The compression is shown in the first page of the maintenance standards section near the front.

acceptable compression for honda gvc 160

thanks for the link but what I was looking for was a reasonable range for a compression test of the GVC 160 engine?

What pressures are you seeing? Are in the ballpark of the factory spec or are you grossly above or below?

I always view compression tests with a bit of suspicion since there are different things/tricks you can do to change the results. Is the engine hot when you perform the test? Do you rock it back and forth to find the best piston position for good compression. Did you pour some oil into the cylinder to help seal it?

4-stroke engines typically need around 90 psi to start easily, more is preferred. Some small engines won't show that much during a compression test because of compression releases and other things. On a small engine, a leakdown test is much more informative and less misleading than a compression test.
