ECHO Echo, Echo, Echo

Looks like excessive inflation hit the 7310. Sawsuppliers was always the cheapest place to get a saw. Now, the 7310 is more expensive, than a new makita 7900, and comparably priced to a new husq or stihl of the 70 cc class.
About a $179 jump in price! Now $100 more, than what a full wrap version went for a few months ago.

Dang. Hope the 4910 stays@$359

 

[karrl]

Woof! I like my 7310 but that’s crazy. Looks like the full wrap model will be over a grand when in stock. Gentlemen’s end of month Husky sale might be the last cheap deal on saws for a long time.

And that’s powehead only.

Yep, sawsuppliers "tries new things". Theyre gracious, but they are not a saw shop.

Few months back, got a complimentary pair of large aftermarket cs 620 felling spikes with the purchase of a new 620pw. That they were going to start selling them.

No harm done, took em out of the package. CNC cut sheet metal. Laughed my a s s off! A small child could bend them. Got a good laugh outta that.

Howdy Echo fans!

Never been over here before but I have a question you guys might know the answer to:

Is it possible to put a 4910 jug on a 490? I've got a nice clean one here with a smoked top.

Thanks!

 

[FergusonTO35]

Don't know about that one, but a 501P jug will bolt right on and give an instant performance boost.

I believe it will swap on, if the 501 swaps on like above poster says, then yes 4910 will work. Intake boots and clamps are different iirc, the rest should work.

You are correct! The 490 intake is round, and the 4910/501p is oval shaped.

Correct, I think the 490 boot may still work as the 4910 boot is actually round before you stretch it over the intake spigot, but the clamps are different for sure.

 

[FergusonTO35]

Awhile back I compared the parts listings for my 500P and the newer 501P and the 501 jug appeared to be a direct swap.

 

[Sawdust Man]

I want to convert my cs3510 to .325 chain, anybody know the part number for a .325 drum that will fit?

 

[mainer_in_ak]

Old news to many, but wow what a great experience working over an old echo cs 6700. About 15 hours of work. Picked it up for $225, looked like it had a rich tank or two run through it, if that. So much saw for cheap.

Stock, it felt slightly less than comparable vintage 66 cc saws of the era, like the husq 266 se, stihl ms 038 super.

Will run it against the neighbors Stihl MS 044 tomorrow. Might be close, I dunno.

Much easier to build than the last basket-case Stihl MS 310 I built. Less parts too.

Its going in a Granberg G777 small mill and will be equipped with a 20" GB 3/8 low profile bar, GB 3/8LP-7 rim sprocket and Stihl pmx ripping chain. Bar and chain shipped from Australia, finally cleared U.S. customs

**Thanks Whites Forestry for the GB goodies, you guys are great.

**Thanks Nick Stoeckel/Red Beard Saws for the stihl-to-echo bar adaptors.

**Thanks Saw Again for the new clutch drum,bearing and rim sprocket.

**Thanks Wolf Creek for the Timberwolf 24" bar.

14 lbs 2 Oz empty/dry powerhead. Not bad considering a metal fuel tank and metal rear-handle. Noodled 22" long x 18"diameter pieces of frozen Alaskan birch to tune it, she pulled hard. Mostly mid-range grunt. From initial test cut before modifications, gained about 800 rpms in a hard cut with rich tune.

Will mill the fk out of this saw while I wait for my ported echo cs 1201:

Over 20 year production run on the mighty 670/6700. So many oustanding instances of superb engineering and other obervations, when you start tearing them down.

Just basic/mild stuff:
.010 base gasket delete
Raised exauhst port roof 2 degrees
Widened/polished intake port
Polished/widened lower transfers
Opened up muffler, but kept that scavenging tube/chamber
.015 off the fly-wheel key for timing advance.

That’s the saw model I first started chasing firewood with back around 2000. Solid saw. It’s been years but if I remember right the air filter would clog pretty quick. I kept an extra and a jar of gas to soak the dirty one in the truck when I was cutting. I would usually swap it once or twice throughout the day. Could have just been the dead Ponderosa we were cutting. We’re feeding a kiln then, doing 12-15 cord per year. Never had to fix a thing.

Ketchup, thanks for sharing. Very typical of these old echos, work em hard for years, and they never beg yah for parts.

The oiler on these things are crazy. Do the typical check on the oiler with bar-tip near cardboard. Looks like snot rockets are hitting the cardboard. Silly to even check the oiler on these old echos, its a press-fit metal oiler gear. They never strip.

Even though it gained good rpms on top, throttle response and more torque down low, the saw still likes to settle into its mid-range powerband.. perfect for milling and staying cool after repeated 16 ft long ripcuts.

That mid-range cut speed will feel kind of "blah" to many sawmen.

 

[mainer_in_ak]

Annialated a ported ms 310 in 22" frozen Alaskan birch, even set pig-rich.

Tuned the carb slightly lean, just to the point where the rpms peaked from a rich tune.

Just radiused the depth gauges on a half-worn 3/8 exl chain. Brought the depth gauges down to .040. Sharpened the chain with an undersized file to get the gullet smooth and sharp. Came up on the file strokes and brought each tooth to a razor-sharp hook with a deep Gullet.

Pulls an aggressive-sharpened chain right in that same mid-range powerband. Going against the other neighbors stihl ms 044.

 

[mainer_in_ak]

Was right about even with a stock 044. In a couple Alaskan birch, decent place to be at only $225 for an underdog-echo. Good reminder how potent a stock 044 is.

The 044 was equipped with a 20 inch bar and full chisel stihl 3/8 chain, and the echo cs 6700 equipped with a 24" bar.

I would beat the neighbor by 1.5 seconds when he was running his saw.

When he timed me running both saws, I would get identical cut times right to 1/4 of a second.

Echoes seem to be detuned and over-oiled from the factory, I think that is one reason they last so long.

 

[mainer_in_ak]

Ferg, in some instances yes, but others, no. My echo cs 530 was a high-revving animal in stock form. The first time I ran it, I was coming from a 455 rancher. It was hitting over 1000 rpms more in the cut, against my rancher.

My stihl ms 290, and the rancher went bye bye.

Now ported, that 530 clamshell animal is 1 second behind my 620 pw in 12" hardwood. It's much faster than my echo cs 4910 as well. Higher stock compression over my 4910.

 

[FergusonTO35]

Nice! The 530 and 550 are two that you never hear anything about.
