Got out a little today ! Got a new tach...(more on that later)says 14900 rpm where my ear set it last week. Think I'll leave it . Sounds good ! Cutting some dirty dragged around wood...so she will be in the vice many times ! I've read many reviews on the saw. Either people like it....or they don't. It's no 550xp....but its not suppose to be. But...I've had many sub 50cc saws...and this saw is by far the best limber.....and actually bucks 6 to 10 inch wood really well too...just not at 14900 rpm lol !
