I just bought a brushcutter from a farm. I'm going to guess it'd be a 70's or 80's one as it has a thumb throttle instead of the plastic trigger. For the model I can see FS then the number is rubbed off and it looks like AV was at the end. It says electronic below that. It appears to be mostly metal including the gas tank Air filter is square not round so it looks like I may luck out and have the Walboro carb but other than that my research is coming up empty. None of the manuals on the stihl site look like what I have. I'll try to post a pic or two here. Any ideas? Thanks for the help!
