I have a 560xpg as well, but haven't been able to use it much because of health issues - so I didn't mention it.
-
The all time preference in the woods here no doubt is the NE346xpg - not much to discuss really. Excellent handling, ergonomics/user interface, accelleration and overall performance!
-
I don't know anything about that, so I have no opinion.
-
Stihl still is a privately owned company isn't it, not one you can buy shares in on the open market?
-
I stopped greasing bar noses about 10 years ago, and never had a single failure, except the occational "chips freeze-up", that is easily cleared. The bar oil takes care of the lubrication, I assumed then - and still do.
-
May well be the case - I have seen several differen tversions on why the deal was done - but the important fact actually is that it was. Exactly what the deal cover is of course a business secret, nothing odd with that.
-
One story (and the most plausible one I've heard/seen so far) is that it was the EU that persuaded Husky to let Stihl use some of their patents, to avoid a "monopoly" situation. I don't know the formal or the practical aspects of the deal though.
-
Obviously false "information", that doesn't add up with any facts - and there never has been documented a single issue with the AT itself on the 560/550 series' - only carb issues.
-
Yes, unless a few of the 575xpAT actually hit the market somewhere - but I believe it was transformed into the 576 before it reached the market anywhere. I had some correspondence with someone that was "user testing" a 575xpAT back then.
-
At least it is a very good saw - but it is hard to guess what you will need in the future!
-
The "gearing" of 3/8"x7 obviously fits the saw better than .325x7 does - but you may get a different result if you put an 8-pin on the 560xp - or you can just put a small spline 3/8"x7 rim on it - or convert it to standard (large) spline (like the 562 usually comes). It may also be that the chain on your 562 is better than it was on the 560(s) you tried.

Autotune (early version) and part of the "strato" technology, as far as I know. They have of course also adopted some older "Husky" features, but those weren't patented, as far as I know. The "Air Injection" never was patented, and the origin of the feature has been debated now and then. Two facts remain, something like it was used by at least Pioneer and Remington in the 1960s, and the "final touch" that made it the "Air Injection" had its first documented appearance on the 262xp in 1989. Saws like the P7700/2077 didn't get it before 1992 (model year, could be late 1991). The still open question is when the 2051 got it..... If it was Partner, Jonsered or Husky that first dug up the ol' 1960s design and started working on it is an open question - but the Swedish production of all tree brands happened at the Husky factory anyway at that point.
-
The engine and everything else that has to do with performance is exactly the same as in the 560xp. All that is different is the bar mount (large), clutch cover, taller air filter & cover, and one part in the oiler (to cope with 28" bars) - and some extra weight. A lot of people in the US would rather have the 560xp, but can't get it there, so they end up buying the Jonsered 2260 instead.
-
They both make their own definations, tailored to make themselves "first" - but it just is BS, as none of them even was close to first - by more "neutral" definations.
-
Husky "loans" a few things to Stihl - but not to Dolmar, that I know of. Dolmar had to work their own way around the patents, which seldom produces stellar results.
-
Fits well with my impression.
-
85cc doesn't sound right, likely a 87cc 288xp top end? ...or just a misunderstanding of what actually was done?
-
Not a thorn at all, but the saw are what they are (as always).....
-
Be aware that the Sugi combination K095/K041 (AT) mount has been reported to cause oil leaks on K095 mount saws with captive bar nuts. I don't really know how serious it is. I have seen Echo ads that show what appears to be rebraded Sugi Light bars, but don't remember which market it was on.
-
Well, torque is of course important, but it has to be in the right part of the powerband - ref. my earlier posts here. Max torque at low rpm mostly are of academic interest. I don't use any Echo saws, for a large part because of low power to weight ratio and availiability here. The 620 surely represents an improvement - but it still is too heavy for the Power.
-
Who really cares?
-
Right, if someone does, either the saw is too small for the task at hand, or something else is wrong. Cutting will be slow either way. What is interesting is how the torque curve right below and over the max hp rpm is (to keep the rpm up), not what the max torque at low rpm is.
-
Well, about that issue - others can and likely will appear.....
-
OK, I see. I will stop complaining then!
-
Just a guess here, but I am pretty sure the 390xp will have the upper hand if both are properly ported, and with a proper carb - but that won't happen when both are stock.
