A good friend gave me this saw out of his dad's garage -- his dad passed a few years ago and the saw has just been sitting around. It's got a new 16" bar and chain, and looks great from what little I know. My friend put new gas in it and was able to fire it up, but it took quite a bunch of pulling to get it running. I don't know really anything at all about chainsaws. From reading here, it sounds like you folks have a favorable impression about Stihl saws. I'm reading through the online manual for operational tips. But wondered if anyone has a shortlist of things I should do to tune this up (like a new spark plug) before I try and use it? Thanks in advance for any suggestions you might have.
