Aut cum scuto aut in scuto
Got a Stihl just like that. Sucker cuts through wood like it was paper. My 75 year old neighbor gave it to me; his dad owned it at his home on Whidbey Island in Puget Sound. I took it to a mower shop to get it cleaned and tuned up, and the guy there offered to buy it from me, even though they sell Stihl products themselves. Good saw.
Same saw the Cowman had, we used to cut better than 8 cord a summer with that thing and never a hiccup.
