Well maybe I should consider that, cuz 150psi at sea level is like 132psi here.
I know that Stihls last a while. But I have heard the 660 is a turd, and my dealer only has one, and its only 100 bucks less that the 661.
But, I am not sold on the 661's fuel and air system longevity. I think it will take a dump, personally. That is why I am considering the 390 (don't want a 395). Dunno, maybe I should consider the 660, but I gotta buy a wrap handle for it.
Send the 660 to TreeSlingr. He knows how to make them run like they're supposed to.
Weber Custom makes a great full wrap for that saw.
