Those are faked as well, but at least the ones I have seen have actually been copies - not quite the same story. Actual copies of the MS380 and Husky 365 also are common, but they don't perform or hold up anywhere close to as well as the originals.
-
One of the typical fakes - it isn't even a halv assed copy, just a lie! The saw is one of the Chinese backyard copies of an old Zenoah saw, in the 52-62cc range - made in any colors, to put your own decales on, if you buy a pallet.
-
The selection of Sugi Lights still aren't what it should be though, without small Husky mount bars in 3/8", and in 16".
-
Not particulary, and it is the torque "backup" right below max power rpm that is interesting, not what it has at 6500rpm.
-
+ heavy and bulky, but maybe not as heavy as the Echo 620. Torque as far down in the RPMs as 6500 hardly is interesting.
-
Another thing is that manufacturers weight specs tend to vary with what sourse you look up/at, and power specs only tell what is supposed to happen at one point in the powerband.
-
The 560xp is much lighter than the MS362, more than the 300g that the specs show. The most important difference is that the 560 is a much more nimble and well handling design though, and performs better as well in the real world.
-
We all have brain farts now and then!
-
I Wonder who created that "reputation", and for what reason - as there have been no indications that it is true on any of the many saw forums I am on.......
-
The 5.5 kg isn't true, and not the power output either. The "ace" used to be the 62cc version though, not the 56cc one. The slowpoke you refer to likely is the 165, that is nowhere in the same class as the 162, despite slightly more cc (not 65 though)? I don't think the 162 still is a current model, for emission regulation reasons?
-
I have more correct info on many of the listed models - but not the complete picture with good enough reliability. I would never publish such a shart, even though I have made similar ones for my own use in the past. One more thing, the listed power to weight ratios contain more decimals than the input - so they would be misleading to some degree even if the input was true. Further calculations on already rounded off numbers is risky business....
-
Those Efco models are know for "optimistic" specs, and the weigh is for unheated ones, while many of the other saws in the sheet are heated. The result is misleading, but the 162 still had a good power to weight ratio.
-
Comparing heated versions of some models to unheated ones of others are of course misleading.
-
Your "power to weight" numbers are turned upside down - and you seem to assume that the specs are always correct and accurate. This is far from the case in reality though
-
Hard to say without being there, but I'd start with checking that the bars are getting enough oil, make sure the tips are kept out of the dirt, and make sure excessive pressure isn't exerted on the tips. I've never had a single bar sprocket failure with either Oregon Pro-Lite or Husky made laminated bars - but then I am not a pro user.
-
The only Sugihara bars I know anything about is the pro grade Sugihara Lights. I can't comment on the others.
-
The splines are on the clutch drum, not on the crankshaft.
-
If you have a problem with the sprocket failing, chances are that you are doing something wrong, as it isn't normal. Greasing the tips or not is debatable. I stopped doing it about a decade ago, and never had a failing nose aprocket.
-
Most Husky RSN bars are Oregon Power Match - decent bars, but nowhere close to SugiHara or Tsumura (or Cannon).
-
What pitch did you use on 3/8" chain in those maths? Also, the speed at WOT out of wood will of course be much higher, and in the wood it will vary over a wide range, so it is just theory to calculate at a set rpm. I'm sure you know this, but someone that doesn't may read the posts here.
-
On some 60cc saws as well, and there are both small and large spline drums made for many saws.
-
There are 3/8x7 rims out there, for both the small and the regular (large) 7-spline drums, but .325x9 (and 3/8x8) is made only for the regular (large) 7-spline drums, except maybe by some "costum" brand. .325x9 or 3/8x8 are too large for that saw anyway, so there is little point in trying it.
-
...and are large and clumcy for a 50cc saw, while the 550xp etc are really neat and well handling saws.
-
Even when clean it blocks about 20% of the outlet. I routinely remove them on my saws, as there is no need for them here.
