I went back to the pawnshop to take a more informed look at the 394xp.I didn't have the tools to remove the muffler so couldn't look for scoring.It started and ran but didn't seem to have a lot of compression when I pulled on the rope [ pulled it without using the decompression buttion] I decided to pass on it.On the other hand,he also had a real clean MS460 magnum that I somehow overlooked the first time I was there.He's got it priced at $300 but he may come down a little.I came home and researched it on AS and Stihl's homesite.To good of a deal to pass on so I'm going to pick it up asap.Wish me luck on it.
