I was given a MS170 by a friend who couldn't get it to run, and he just wanted to get rid of it. I cleaned it then emptied the old fuel & oil because he couldn't remember when it was put in. Filled with fresh fuel & oil, and fingers crossed I went through Stihls start procedure. It took a while but eventually I had it running. Next thing was to upgrade it - a dog was installed along with the side chain adjuster - it is a pleasure to use with the 14-inch bar & chain which suits our Australian hard woods. My MS251 with an 18-inch bar & chain does the heavy work. Stay safe.
