I'm going to get my dad a stihl MS 250 saw for fathers day. Dad had both of his shoulders fixed last summer, and i was considering getting the easy start version to help with his shoulders, but to get the easy start you also get the tool less chain tensioner, and I've never seen anyone have any luck with them, granted these were not stihl saws but it still makes me leary. So do any of you guys have any experience with a stihl with these features, namely the chain adjuster, and easy start? I have a 460 magnum and love it but its a regular compression release, manual adjust bar. Thanks in advance.
