Sadly for the echo believers what the troll says is true, the upside is that they merged with shindaiwa which produces a much better product. Echo have products that are good but not a complete range that is good. They are well behind the eightball with emission compliant engines and are not leading in any useful technologies. Having said that I have a top handle 23cc makit made by Yamabiko Japan and its dead reliable and I use it a lot. Max unloaded rpm is 10k, but it does the job. A ms150 makes a good 30% more power but is 4x the price. If the 590/600 series echoes cost what huskies & stihls did, would you still buy one?

Well as far as I know all ope is a compromise on something. At least I have not found a perfect one for me yet.
I also know that data sheet numbers are a small part of the real world use ability and personal needs.
Like those vibration numbers. I have arthritis and carpal tunnel so vibration or lack there of is a big part in my decision. While shopping for a saw I used saws with "better numbers" but that unit numbed and made my hands ache worse then what some would call a lesser saw or not a top notch saw.
But to me the lower numbered saw was a over priced piece of junk even though many say it is a superior saw. To me I just laugh to my self and think poor misguided soul.

No chainsaws have their rated max power at 14.000 rpm. Most fairly modern saws have the max output at somewhere between 9.000 and 10.200 rpm.

Max recommended rpm (that often is about 13.000 - 14.000) is a different parameter, that has nothing to do with the max power output.

If the specs for a saw says "4.2 HP @ 14,000 RPM" it either is a misprint, or it just is a sloppy and misleading way to state that max power is 4.2 hp and max rpm 14.000. I have seen it done (but not with those exact numbers).

Yeah, I know. It was an example with extreme numbers. ISO8346986429846 and IRAM3246324786 don't exist, it's just to state that power tests are tricky...

I think some guys are power at high rpm, and low weight fans, and that's ok, but some of us are looking for decent power, reliability, durability, torque, etc. A good example is Echo CS-510, plus it's really easy to mantain/repair. Some new saws with rubber intake develope air leaks too soon. Yes, maybe they are smoother, but not as reliable as an old plastic or metal intake... And I'm not talking about Stihl and Husqvarna, my Echo CS-350tes has its carb mounted on its handle and a rubber intake. Guess what, it developed an air leak with less than 20 hours of use...

Personally, I prefer old proven designs...

Are you saying the 510 doesn't use a rubber intake boot?, I know mine does, and all others, don't get me wrong, I love my 510 and 520, both are excellent runners and great firewood saws......:thumbsup:s-l1600.jpg

I really don't think Echo has ever really tried to get hung up In the "our saws are better than their saws" scene, true, their saws are choked up from the factory, and some models I wouldn't even consider, but there is a few in the line up, that with little work, become very good saws, am I a "echo only" guy, hell no, but I do own several certain models that I'm in no rush to sell, am I sold on strat saws or autotune saws, hell no, I've actually gone back to old school designs, I still feel it comforting to see that echo still has a couple saws in the line up that have been around for nearly thirty years, the 670/680 and the 800/8000, both very well built saws, and again, with little work become excellent saws, and I must lastly say with all do respect, I'm just an average firewood hack, otherwise my outlook might be a bit different......but not much......;)

They aren't that tricky, when you have a properly constructed, calibrated and certified dyno. The real issue is that the specs only is about the max output and the rpm when it occur, so it just is a "snapshot" of one point of the power curve.

Ohhh, I never had to disassemble my 510, I thought it was plastic! :yikes:

Maybe it has no movement like the CS-350TES one? The problem with 350 is the rubber intake and all the lines move with AV system...

And what saw would you choose? Both imaginary

1.- 4.2 HP @ 10,500 RPM and 2.5 HP @ 9,000 RPM
2.- 3.5 HP @ 10,500 RPM and 3 HP @ 9,000 RPM

I would go with the second. It'll be easier to keep the saw running at 9,000 RPM and it would deliver 3 HP. The first saw's 4.2 HP are pure marketing.

I'm not telling Stihl/Husqvarna vs Echo case is (or not) similar to this example. I'm just trying to explain why HP ratings are not so important to me. Maybe I'm wrong, I don't know what to think after this thread...

Don't think I'm an Echo only guy! I have a Stihl and some Husqvarnas too! I like Shindaiwas 757 and 488... I love Makita/Dolmar and I like some Oleo-Mac saws...

I have been looking at their weed wackers and brush cutters or their multi head setup.
The new 2620 looks neat but I think it has a non adjustable carb.

I've had A Pas-266 for 2 years now.
I have:
- Curved Shaft Edger
- Pro-Torque Trimmer
- Brushcutter
- Articulating Hedge Trimmer
- Power Pruner
- 2x 3' Extension

Anyone can say what they want, but it's been nothing but good to me.
The Articulating Hedge Trimmer and Power Pruner are big money makers.
They all do the job and do it well.

If that's something like Zama RB-K84 it's fully adjustable.

Well said, I would never say Echo has no place in the market....ttheyost certainly do. Japanese have a great history in 2t and quality manufacturing, I'd just like to see them take OPE more seriously and make some competitive pro products. They have the plants to produce them, they just need to poach a few German/European engineers to catch up and be taken more seriously.

No, it certainly isn't, and the "shape" of chainsaw power curves aren't likely to vary as much as in your exemple. A saw that was like # 1. above wouldn't have made it trough the user trials, if it ever got that far....
No chainsaw I know of has its specified max output as high as 10.500rpm btw.

They likely need to gain access to some patented technology as well.

Which 510 are you talking about?
CS510EVL (orange, horizontal cylinder, bolt on cylinder ) or CS510 (grey, clamshell construction, etc).
I know the earlier EVL did have a rubber intake.
Never tore into the grey model I had.

CS-510 clamshell. I think they were grey a couple of years ago, but here in South America they're orange.

Great saw, good power, good torque, great air filter and oil pump, not too heavy for it's displacement. I have never had to disassemble it. Never had a single problem. Lots of hours on it and it's 4 years old...

Mine is like this:

Yep, both used a rubber boot......
