What I have here is a Stihl 011 AVT. Bought it last year to use when I climb for fun and now I have 200T and dont need this one. Has newer fuel lines that were in it when I bought it this past summer. I have not run it a lot but it did great when I ran it. I cant check compression but it seems pretty good. 16" bar 3/8 picco with decent wear. Ran great the last time I used it to top three walnuts I climbed. I fired it up last week and it ran good. $100 + shipping from 44720
