Good points. Echo sort of fills a nice gap between the cheap Farmboss/Rancher and the pro lines from Stihl/Husq. It was unfair of me to imply they're equivalent with regard to serviceability.I will have to disagree. Both the farmboss and the rancher are clamshell cases and not easily split rebuildable unlike the Echo. I also find the Echo's to be better built than the cheap line of Stihl or Husky...
I'm not sure what to say to this, other than there are many variables in setup, wood, and expectations. I run full chisel chain (Stihl RS or equivalent) and set my depth gauges around .031", which takes some power to pull. I'm cutting mostly red oak, and a lot of logs large enough that the nose on my 20" bar is fully buried. I've never put that combo on any saw of any brand under 65cc and not been disappointed with how gentle I have to play it to avoid bogging. Yes, it will cut, but my God... annoyingly slow by comparison to a properly-matched motor/bar configuration.And I can run a 20" bar on my Husqvarna 550XP MKII all day in hardwoods without it skipping a beat. It's a beast of a saw! My Stihl 261 will also run a 20" blade as will my Echo 590. But typically when I need 20" I am using my Husqvarna 562XP and she's a screamer. a 50" saw isn't an ideal place for a 20" bar but some saws like the 550+XP doesn't bat an eye to it....
Ignoring my little top handle, the combos I'm running today are 19" on 65cc and 28" on 85cc. Both full-comp 3/8" full-chisel RS on roller nose bars, standard 60/30/10 sharpening angles, but with depth gauges set down at .031" (factory is .026"). They pull hard and cut fast.
If I were to try to run a 20" bar on a 45-50cc saw, I think I'd set the depth gauges up around .020". That would prevent bogging, but it's going to cut 30% slower, taking a smaller bite with each tooth. Most people never adjust their depth gauges, which could explain most of the difference in experience/expectations.
