Now you've got me curious. I've been searching trying to find this thread but so far, no luck.
So 120 psi is too low? If the saw hung while held by the starter handle, would you guess that the 120 reading is wrong?
The thread is "Stihl 650 or 660" about halfway down the page. I was going to ask him if this was him selling it. 120 is low it should be up around 150 maybe more. The 140 -150 range could be acceptable too if you can get a good look at the internals. Its hard to say how accurate the pull cord method is. It is worth the $25 to get a comp tester and also look at the exhaust port through the spark plug hole while you've got it out with a flashlight.
