ECHO Echo, Echo, Echo

[mainer_in_ak]

Joe, I'll tear em down and measure the transfers, squish and compression. I'll post up pics of the cylinders. I'm curious about this too.

 

[RCBS]

Echophiles...should be easy question on the 620? What's the deal with 70 drivers on 20"? Is this the Echo bar and can be changed by using different bars, or is it the way the bar mounts. Can I run 72 drivers on 3/8?

Thank You

Well I finally got a 4910. It's very pleasant to run, quiet, easy to start, light and cuts little stuff pretty good with the 325 chain. I'm going to run it awhile like this before I make any changes if I do decide to make them.

Cant get them in Ireland at all, they had them when they came out, but they probably couldn't charge
enough for them else they would have to put the prices of the CS501 up even more to leave a gap
between it and the 4910, sad, as its lighter than the 4510, and that is why I won't buy a 4510, same
weight but less power, makes no sense at all.

The 20" tsumura bars are 72 drive link:

Slight discrepancies like this are usually just because of whatever bar and chain the OEM is using. My Echoes, and every other saw I've had for that matter, have worked just fine with whatever the maker of the bar and chain recommend.

It is the Echo bar, you can change to 72DL only if you get a bar that is advertised to fit 72dl on a Echo.

4910 was never present outside USA. 490 - yes.
If you hate 4510 for 300 grams maybe it’s upcoming 50cc “twin” 4920 will be a bit more interesting? (on the bonus side there are spring AV’s with ~30% less jiggle?)

Just tore down a non-running qv-6700 rescue saw.
It was overheated. You could see where flames melted the side vents. The rubber plug for winter setting was also missing. The clutch cover was burnt.

When the older style handle-attached chain break was broken off, they simply replaced it with a newer style one.

Removed the cylinder, piston had rubbed off only near the exauhst port and seized the rings. The muffler screen was melted, probably from scavenging flames from a house fire.

Cylinder looked horrible, all around the exauhst. After some careful scraping and honing with 220 grit using sea foam deep creep, not a SINGLE gouge through the plating. Gawd, Echo had some THICK plating on these brutes. Un-fkn-believable!
Saw will only need a piston and rings.

Cosmetically, its rough, but it has character and a story. It probably saved lives. I pulled out some chunks of vehicle and asphalt shingle out of the fly wheel fins. I bet in a last-ditch effort, they must've used it to cut into cars in order to save someone. They weren't designed for that, so many of the handle screws were loose, from the vibrations of cutting metal.

Many of the carbide teeth were missing from the Echo Quick-Vent chain.
Looking forward to giving it a good working retirement, as a firewood saw. It's just gettting warmed up, even though it has been flame-treated:

I saw the 4910 saws advertised on the sites in Ireland, but never seen one here at a dealers.
I had 3 CS501 saws, they were well built, I had a Shindaiwa 490 before them, I liked it more,
think it was 490, wish I had of kept that one, it looked like this,

So what is the 4920 in aid of, is it a 50cc saw, that would make three of them, the 501, the 4910 and the mentioned 4920.

Its not just the 300 grams, its the lost power too, so I would rather have the 300grams more for the extra power.
I see there is a CS4010 available in Ireland, is that saw available in the US, I don't think I have read much about it,
must have a look.

 

[FergusonTO35]

Around here at least, Echo weedeaters and blowers move a lot faster than saws. It's not uncommon for dealers to have saws from the few years ago still NIB.

CS-4910 is just a 501SX with plastic handle & rear grip, simpler spark plug connector, stainless steel sprocket guard plates and laminated bar. US-only, regardless of online ads.
Shindaiwa 490 is actually an older thing derived from 488 (produced from 1988) while the 501 history looks like this: 466s -> 452s> CS-490/500 -> CS-501/4910.
As I mentioned - 4920 is a reinforced twin brother of CS-4510 with bigger bore & stroke. Slightly better curve than CS-501 but basically the same power range with every other feature being same as CS-4510.

CS-4010 is a 40cc thing replacing CS-420 so it is just offtopic in this case

I know what the Shindaiwa 490 is, to me they were a better saw than the CS501, which buzz
through the handles, I had three, all the same buzz in the handles.

I commented about the 4010 as I know nothing about it, and you seem to know
about the brand, if it upsets you that more than one saw is being discussed
then ignore my posts, you seem to have some sort of complex.
You also forgot a very important detail regarding the differences between
the 4920 and the other 50cc saws mentioned, that being whether the 4920
is a clam shell or split case.
And no, please don't answer, its easier to look this up elsewhere than be
talked down to by you.

Probably some sort of misunderstanding as I definitely was not intending talking down to anyone (not English native anyway, so things probably happen).
I apologize if it sounded this way.
Also I don't really feel upset (why should I?). Not sure about the complex thing too

As for 490 (Shindaiwa) I meant that the chassis is just an earlier development than 446->501 of the same Shindaiwa team and that's it, no feelings attached.
And yeah, the outdated AV of that chassis (501) is clearly the worst in entire Echo lineup.
As for 4920 - it is just as clamshell as 4510 is (also 4010) - they are all farmer saws = plastic chassis.

As for 4010 - new engine, strato like all other new ones, no cat, like all other new ones, 4510 clutch/brake, 041 mount, 4510 shaped rear handle grip (different than 3510), flip-lever caps (in EU version), 4510 style clutch cover (outboard BTW), 3510 (same) top cover clips and spring AV.

Some things we should all remember: A. Not everyone here is a native English speaker so some things will get lost or changed in translation. B. Conversations online don't have any of the non-verbal aspects of talking in person or even on the phone. Meaning, it's harder to find implied meanings in what is said and easy to misinterpret things.

My only entry is this JD stamped Kioritz . Haven’t had it long,got it sans bar and not running , fixed the usual culprits is all it required.slow and heavy but it’s got grunt and sounds really healthy!

My buddy has one, but the Echo CS750 equivalent JD.
I talked him into buying a 28" Tsumura for it.
Should be a sweet combo!

 

[FergusonTO35]

Those JD Echoes and 1970's Sears Poulans are the best looking rebrand saws of all time, methinks.

Today's chainsaw adventure:

Overflow filled my side-channel where I park my river boat. The river level came up over 3 ft in the dead of winter, because of a warm-spell. What was once dry land where my boat was 10 ft away from the ice, is now 3ft of solid ice. It even poured into the treeline.

The fkn drain plug was pulled. The boat filled with water, and froze into the overflow. Not only is the boat frozen into a ft of overflow, it's filled with at least 800 lbs of ice.

I'm undecided what to do:

Build a tarp-tent around the thing, and thaw it out with a wood stove and chip away soft ice?

Or echo chainsaw that fker till she's clear of ice? Im worried that as I cut on the inside and outside of boat I may accidentally cut the hull.

 

[Thesandman]

Is that boat a echo?
