When you talk about the chains. I've been trying the 8ten chain and I feel the same. Cost is great but don't matter how I sharpen it or adjust the rakers it won't cut like stihl rs
It’s so kooky. Every way you try …is just a rabbit hole. Echo knows most people rarely use their chainsaws. So they give you a 5 year warranty 2, if you’re “commercial”. They say it’s compression but it is twice the wear on your rings and cylinder walls and parasitic drag …So you go back to the saw that sits in the floor, and the guy can’t believe how long it’s lasted. Years, decades. Assuming it made it past the bad gas hurdle. Then you give the pro a 590 and by the time the ring wears out it’s already paid for itself and a ring job would be due anyway and why get the dual ring & 2 year warranty if it’s $300 more, right? But it does have less drag.. I swear the only thing I can think of is the starvation if any between the rings. It would have to only be of benefit right before its end of use. Because the two rings have gone past break-in and on the way to worn out the ring tension came off and freed some revs. This would be a saw I’d experiment with grinding the rings loose. But, cause & effect. Nothing but a rabbit hole.
Come to think, maybe Echo did loosen the rings as part of the 620/p package and that info just hasn’t trickled through. That is a possibility and now wouldn’t that be cool. Two backed off rings seems to me would help the compression stay in longer add longevity and reduce parasitic drag… seems that would add power… dang rabbit hole!!
Great runners👍🏻 customer knows best!
97 is to much. 99 100 is best
looking good. thanks boedy

Echo uses barrel faced rings. Other brands i have seen with and without chamfers on the edges.
Dual rings only helps on a psi gauge. Nearly irrelevant while running and has no bearing on compression ratio.

Sounded like the 97 saw had an occasional miss...... may be just my ears.
It was eeeever so slightly rich there at the end. I could lean it out and it would go away. Was totally jetting.
ps. no snakes
👍👍knees….i feel you pain….daily.
102° saw appears to have more torque… Good job on both!! Nice comparison!!!
Looks to me like they run great!
