I have noticed, however, that the modern Stihl products do not have the longevity of the old Stihls (in the smaller sized models). I've switched to Echo for small sized chainsaws.
My 026 runs and runs. Never a problem. I had a Stihl 180 for light work. It always had a flooding problem and then one summer, it wouldn't start. Took it in, and they informed me the cylinder was bad. It was a 3 year old chainsaw with only a half dozen or so tanksful of fuel through it. I went back to my old (as in 12 year old) Echo CS3000 and tuned it up. Same thing happened with a Stihl weed trimmer.
I run the same mix in all my 2 strokes (all within the manual specs) and have to think that the smaller Stihls don't have the engineering and manufacturing that the older models (and likely the larger models still have).
