Ok, so I love saws more than I NEED saws (see my signature). I have a "new" MS290 that has only been used for a few hours (like 2). It's out of warranty, so I did a muffler mod on it and re-tuned.
I know the factory says something like 12,500 max RPM, but here's the twist.
In reading after searching, I find that saws tend to creep up a little in WOT RPMs as they break-in. I tuned by ear and then tach-ed the saw, getting about 11,500 RPM. To my ear, 12,500 seems above the four-stroke fade out.
The question; think I can tune it up to around 12,000 or should I let it settle in where it is first?
