I loved those little echo edgers I had one used commercially for 9 years best edger I have ever owned my 2 Stihl edgers yes more power but havier and not as reliable at all as my echo edger was it probably would have lasted me longer if I had not run it over with my truck
Great repair video especially where you show the magic air/fuel mixture screw location. You may want to mention about richening it until it runs rough or 4 stokes, then lean it just until it runs clean again. No leaner. That's the sweet spot. Thanks
