Thanks in advance.

In "new" condition the 226 will run 110 to 120 PSI. I suspect this one has been sitting for some time and the rings are stuck. You can try some ATF in all the cylinders and let it soak for a week or so. Turn it over by hand every couple of days working it backward and forward. Also check for stuck valves which you should be able to see through the spark plug holes. You are not likely going to get it started with the pressures you are currently showing (at least with the starter) If the pressures come up quite a bit after soaking you might get it started. The other trick you can try is to pull start it. If you manage to get it started the compression tests will likely yield much better results after it runs for a bit and gets hot and things get loosened up a bit.
