It is about the thickness of the upper part of the drivers, and the resulting kerf width. With Stihl chain it is .063 in .050, .058 and .063 - with Oregon it is .063 in .063, and .058 in .050 and .058. This is true with regular chain in 3/8" and .325, but it isn't a big deal in practical (work) cutting. Any difference in cutter width (by design, or because the cutters are filed back) is another factor.
-
With Stihl chain there is zero difference between .063 and .058, with Oregon there may be a slight one (.058 cuts a narrower kerf). The bar or the gauge isn't the reason if a 372xp doesn't pull a 24" chain satisfactory (for most people) - the most likely reasons are a badly tuned saw or a dull chain.
-
There will be no difference in power (caused by design) between a late 266se and a 266xp - but the early (up to some time in 1985) se saws had a smaller carb, and slightly less power. As with virtually every model, there were other changes as well during production, but I don't know of a single one that happened at the same time as the designation/labels change.
-
I stopped buying Stihl RSC/RS some years ago, because Oregon LP/LPX was a bit faster and smoother in my comparisons. The differences are minor though, so I don't mind using any of them (or Oregon LGX). The above is about regular chisel chain in .325 and 3/8", I haven't compared anything else. There was no price difference to speak of here the last time I checked - but I know there is on some markets.

Yes, K153 is an old Dolmar mount, that has been replaced by K095 (Oregon recommends the K095 for the saws that originally called for the K153). I am surprised if the bar you bought is of recent production?
-
It is what it is....
-
Not particularly reliable, but quite nice.
-
The Dolmar is over, bulky and clumsy to handle - and isn't really an alternative to a 550xp.
-
The CS550 is an overheavy, bulky and underpowered saw - there are much better alternatives from Echo out there (even those are a bit lacking though).
-
The use of the word "casing" is a bit confusing here - but believe the question really is about the clutch cover? If so, the same covers will fit all those models (and more), but the 371s and many 365s had a front chain adjuster (and no adjuster in the cover). Different part numbers can be about color, minor changes in production, and of course standard vs. wide.
-
That will do it. However, you likely would be better off with the laminated Rollomatic E that wyk mentioned - but it may not be currently available?
-
Up here (Norway) Echo saws are too close in price to Husky and Stihl saws to be of any interest - but this will vary with where you are. Chainsaw pricing isn't always logic....
-
Not an equivalent, but he must have meant the new 501SX, that has a considerably higher power output than the 500ES/500P (according to specs).
-
I believe the cylinder is different as well, and don't really know what the result will be.
-
The 7900 family use the "large Husky" (D009), the current 5 and 6000 series saws use the "small Husky" (K095), the smaller saws (including the 420/421) use the K041 mount.
-
Sounds like the EA7900 is the same (demoted) saw as the 7910.
-
Are the ones having trouble aware that the "start" position should be used, also when the engine is warm? At least that is how I read the manual....
-
Definitely doable, andmay be even fun. People miss out a lot of fun fun stuff, to apply with what they think are rules......
-
Here is the current Echo line-up (global):
-
Both chains are low profile, but the PMM also is narrow kerf (.043 gauge vs. .050 - meaning you will need a new bar). Issues with the VXL are well known from other saws as well, and the cause said to be the very long cutters. It has Carlton cutters, so avoid Carlton as well. Other .050 lo-pro chains may work on your saw, like 63PM, 63PS or 91PX (VX as well, if you still can find it).
-
Yes, it is!
-
As I understand it, the 385 cylinder is better ported than the 390 one from the factory, so the 390 is in more need of porting. The 385 can gain a lot just from opening it on both ends (carb and muffler).
-
Chisel and semi-chisel both are "standard", it's just a matter of choice (and some times local availability). Ime, chisel works much better than semi-chisel for cutting wood from the side, to split it ("noodling"). Much of my wood is knotted and/or twisted, so I do quite a bit of it.
-
It looks like Oregon has discontinued 36" bars in .058, and list them in .063 only by now. I would look at a Tsumura or Sugihara Light in that length though, if I had the need for one (I don't).
-
Those are options, as is the older PM1. A couple of decent pictures likely would tell....
