Hi Everyone, Having some trouble using a new Stihl FS-80 trimmer I bought. I had been using an older, curved shaft, homeowner model Weed Eater for many years. I have a lot of flower beds on my property that I edge with my trimmer. Although the Weed Eater was not the ideal trimmer, I was able to edge the flower beds with excellent results. Very sharp, 90 degree edges in a short amount of time. Unfortunately, the edging results I'm getting with the Stihl are not nearly as sharp and straight. The two pieces of trimmer line tend to cup into the bed edge, causing a ragged, uneven edge. I've tried a few things that seem to help, but it still isn't nearly as clean a finish as I had with the old Weed Eater. The FS-80 came spooled with .95 gauge line. I went to a lighter .80 gauge line to see if that would straighten out flatter during rotation and give me a better edge. It seemed to help, but it still wasn't as good as I hoped it would be. The Weed Eater did a great job with the .80 gauge so I'm wondering why the Stihl isn't. Should I go down to a .65 gauge line? I also ran the trimmer with only one piece of line coming off the spool to see if that would help (the Weed Eater is a single line feed vs. the double line feed of the Stihl), but again, not much of a help. I've also tried wrapping the line on the spool in both directions, with no twisting and that didn't seem to make any difference at all. I'm at a loss here and was hoping some of you trimmer experts had some advice for getting cleaner edges with the Stihl. Thanks for your help.
