one last time for those of us who cannot see/read past the end of our nose. the saw in question may or may not have an issue. my very well worn 261 is @ 158psi and runs great,with no noticable difference between it and my newer ones. it is up to the OP if they wish to pull the exhaust and check the bore. who knows how it was tested or the quality of the testing equipment for that matter. all i am simply stating is that 150 is within spec, and i have bought/sold many a used saw w/150psi and were just fine. it is really not worth arguing about. the info comes right from the service manual, and i was simply passing it on, no more, no less. no too sure what is dangerous,unprofessional,carless or wreckless about that, other than it gives the "mister look at me" another chance to flap his gums. there are many here who think alot of you and your work, i and i respect that. but there are just as many whom see you for what you are, as i am sure there are those that think the same of me. i personally get a real kick out of watching you run a saw. i just hope you move on to your next hobby, as your kind always do, before you really hurt yourself or someone else.
