Title: Echo 670 6700 680
Post by: Cut4fun on August 19, 2012, 04:26:37 pm
Thinking about taking one in on trade. echo cs-670

Anyone with info running one etc?

 Decent firewood cutting saw? 

What bar length will it pull comfortably in hardwoods with 3/8?

How hard they on parts and is it hard to get parts. I  know the 8000 parts are  :o expensive.  So figuring this might hold over to the 670 too.

Current model is the 680  66.8cc 20", 24", & 28" bars

There's a Echo dealer between you and Bucyrus and another on 42 North edge of Mansfield.

The only bigger current model is the 8000

I have a older 50cc clamshell Echo and for that type of engine, it is made really well. Runs right along with the 52 cc Dolmars.

 I have a Echo 670 and a 044 Stihl, so close in cutting speed I can't tell, on a good scale the Echo is over 1/2# lighter.  The 044 revs higher but the 670 has more balls.  Steve

Man that all sounds good. I told him to send it so I could give it a look over. Thanks for input.

Is there any  difference in 6700 v/s 670 like updates etc.
Title: Re: Echo 670
Post by: mountainlake on August 22, 2012, 07:44:59 am

 Had the 044 and 670 out yesterday, the 044 was faster by 1/2 second in a 10 second cut.  I think the lastest cylinder has a little better porting, most likely room to raise the exhaust port on Echo saws. On a 6700  the newer cylinder needs to have the 670 intake setup as the intake is different.  Steve

When ever this 670 or 6700 arrives I hope you dont mind if I pick your brain with my newbie to this saw questions. 

  I see the IPL showing the intakes. Thanks for bringing that up. I wouldnt have known.

Still isnt here but I was told it has 6700 on it and is grey. 

Do you know if all the mufflers in series will fit?  Was told it needs muffler replaced. So was wondering if 6700 and 670 mufflers are the same.

Did you get any pics of the 680 P+C compared to the 6700?  Is it like the new 8000 P+C compared to the early 8000 P+C differences?
Title: Re: Echo 670
Post by: sharkey on August 27, 2012, 09:22:20 pm
Steve,
Did your 680 P&C kit come with that odd crossed piston and single ring?       

Like the latest 8000 top end the 680 cylinders are coming with the quad port transfers and dome cut squish band/combustion chamber.  It seems they want to sell this top end as a set.  If you order just a piston you get a flat top.  At least that was what was coming earlier this year.  Ill try to get you some pics of the differences.   

One of the Echo dealers told me there were 6 different P&C combinations used on the 8000 since 1986.  8000 piston is not crossed like the 680 and continues to use two rings.

Took echo cs 670 for repair. Guy traded for a stihl 024.  He wanted a lighter saw. Took in with a 18" bar.  Not a good combo for this saw...heats and dulls the chain quickly.  Changed to 24" bar with half skip chain and cuts great. Good power, seems Alittle off balance...like the stihl 361 better, but overall good saw. I will be offering this saw for sale.

 :-\ heats and dulls the chain with an 18"? but is fine with a 24"/skip? :-\
something doesn't sound even close to right.
i'd figure that out before trying to sell it.
Title: Re: Echo 670
Post by: Cut4fun . on August 29, 2012, 02:37:44 pm
Was told I have a box delivered today. Should be the 6700 or a 505.  ;D

I'm going to run a 16" on this 6700 to start so I dont get the 18" to 24" deal  ???

I think running a 24" with full skip would be a good idea though on these from my readings though.   I will run a full comp 16" to 20" on mine when all said in done I hope.

Starts and seems to run good and has real good compression (just from feel starting).

I made sure to fatten up everything with the missing muffler to fire off an see.  :o  Can you say she sounded like a racesaw  ;D.

Looks like I will needing a few parts but no biggie.

 These saws handle real nice with a 20" setup, as mentioned above if it didn't cut with a 18" setup some was wrong with the chain or bar, most likely the rakers too high.  These saws have the torque to handle a agressive chain.  Steve

Looking for max rpm specs on this saw. Right now I have it at 12K and just shy of 1 turn out on H with my 100% synthetic Klotz at 32:1.
Manual says L  1 1/2 to 2 5/8 out I settled on 1 1/8 -   H says 1 5/8 to 2 5/8 out and I went with just shy of 1 turn out to get  12k.  True the carb might need a kit and had sat for years before I got it.

Manual also says CAUTION always tune H side at least 1 5/8 out.  ???  It aint happening she would be so fat it would be a pig. Use commons sense on tuning IMHO.

Also never seen this in print before on sprocket rims wear.  When sprocket has worn out 0.5mm or .020 inch or more replace rim. Measured from top of rim to worn down area.

If you let them rim wear too much, the chain drive links will start stick through the rim and riding on the hub. The drive links will make cavities in the hub eventually.

Rain stopped so I got to do some test cuts.

Bucked some black walnut and ripped cut with 20" full comp in hard maple and soft spruce.  Reminds me of the husky 365 special cut wise.    Modified clutch cover was made for noodling  :D :D :D

I was impressed with this 67cc echo for sure  ;D. RPM WOT ended up 12.3k after the testing. Like it where she is at right now.

To show what 660 is talking about.

I know this works for the 3/8 7T rims. Dont know about all the other in 325 404 or 3/8 8T

This is the worn 3/8 7 that came off the 6700 and you can see wear the drive links were contacting the clutch drum.

mountainlake  did I read right a 8000 carb is a straight bolt on to the 6700 or is 670?  Not that I am going to do that to this stock 6700, cuts fine the way it is IMO.

Just thinking for the guys that woods port and want more carb.

 I had to file a bit on the elbow the air cleaner mounts on as the choke wouldn't close.  I don't think the 8000 carb helped much as I now have a couple other 670 saws that run just as good, should help with a port job.    Steve

Just seeing if I can broaden my search on the clutch cover mainly right now and brake handle. 

Is it only 6700  670 and maybe 680 that fit this saw or is there some smaller saws that might fit too?  Lot of them look the same in pics is why I am asking.

Post by: Cut4fun . on October 24, 2012, 04:42:38 pm
I have a 670 clutch cover with tensioner in the cover in route. When did they start doing that on the 670 run? Mine being 6700 is in case but I'll just remove that one.

Also I'm just hitting a bad having to repair streak right now. Was getting 6700 ready for a test drive with a 20"  I put together for a buyer and dang if the right side handle to motor mount didnt break into.

Hopefully the av might be the same on 6700 670 680 and make it easier on me finding a used one.

FWIW, The 5500 was offered with a 24 inch bar using .325 skip chain.  I wonder how that set up would work on your 6700?  6700 recoil, top cover (plug in air filter) and clutch cover are the same as gray 5500.  5500 has a 1mm shorter stroke over the 6700 so the cases should also be the same.  5500/6700 Bore and stroke 46x33 vs 50x34.  May be just the difference in piston height or skirt length or it may be a different crank altogether.

Have poulan 415  65cc and a friend has husky 365 special 65cc and husky 362xp 63cc  I could compare to using same chain on all.

We ran the Echo 67cc against the Dolmar 6800i.

The Echo was a lower RPM torquer with a 8 pin rim and the higher rpm Dolmar had a 7 pin. The cuts were pretty close though.

The Echo is a likable woods saw

Howdy! First post over here.
my next project is a straight gassed cs 670. Does anyone know where i can find a piston or P/C if I cannot clean up this cylinder?
Can/should I use 6700 or 680parts?
I would prefer to use OEM if possible .
I have looked on fee bay, but was wondering if there are better options.
Thanks!

Nice saws for the $$.  They wake up alittle with muffler modding.

 I dont do the base gasket removals anymore and never did on these.  So I cant help there.

What do you do for your muffler mods. I might as well do it while its off the saw.:)

I pulled the OEM deflector and opened up the exit.   

Now if you felt like doing  alot of work there is a cage inside that could be removed.   Not me though.

Here is what the inside of 6700 muffler cage looked like.  I dont see where removing cage would gain much.  By looking at the one on 6700 they seemed to flow freely.

Here is inside 6700 muffler.

Thought I would give the echo 6700 some attention today on some down time. Have a new carb kit already and was just comparing to a NIB echo 8000 carb I have on hand too.

6700 HDA 76  15.08

newer 8000 HDA 63 16.66         

Thought about slipping the 8000 carb on there but doubt it will make any difference in the stock saw with slightly modded muffler.

I put the 8000 carb on for chits.  Didnt even get it to fire off  :-\. So checked spark. Hmmmm yep something was wrong. I think I may have it so flooded now will try another day. Also need to pull carb again to check 8000 kit. I remember pulling it apart way back when and cant remember putting it back ready to run or not.  :-[

Yep she was flooded.

Had a 18" 20" 24" to choose from and went with 18" for test cuts buried. Ran good.
 Dont know if I notice any difference with the 8000 carb but maybe there was in my mind. It's been a long time since I have ran this saw and know it was going to be needing a carb kit in the stock carb soon.

Think I am going to slip the 24" on it and see.  It just seems more feisty in the cuts now. Could just be my imagination too. 
I may leave the 8000 carb on it and offer it for sale to a local if he trades his other saw in.  Hmmm I wanted to keep this one for myself but I have so many others to use in the cc class.  :P

Hmmmm may see if it can run with my PP415   :-\

Picked up a gently used, clean CS-670 this morning.

has a 24" bar and a couple of usable chains




Man I just noticed your 670 has about twice the height air filter cover and filter then my 6700.

Going to try and make a video with my other camera on video mode. Will do the 6700 and 415 using same chain in same wood. 
Same wood I just shot the echo 4500 3900 with the ps ps3 chain.

I didnt care for the sony cam I just used with all the software I had to load on puter to use. Just want to see if this fuji will be easier on my brain to do.

I'll be pulling this 8000 carb back off after running dry. It was a new in the box carb.  Going to rebuild the 6700 carb and put back on.
Just not enough there to justify keeping on this stock saw.

This 6700 has the stock oem carb back on it. Checked carb over and didnt even need a kit.

Trade for?

I cant figure Echo out.  The early 6700's came with a Walbro HDA-47 carb, which is identical to the HDA-63 except for the length of the H/L adjustment screws.       

Over the last 10 years Echo has gone to smaller carbs on all of their saw engines.  The lone exception has been the cs-620 which went to 15.8 V over the 15.0 V on the 590/600p. 

The new 8000 (800p) comes in with a 15.8mm V carb?  HDA-153 is shown for the final version of the 8000 with HDA-324 listed as the new 800p carb.  Both are 15.8 V with the difference being the fast idle is on the choke pull of the newer carb.  Why would Echo spend the time and money engineering a new cylinder and piston (quad port hemi head with the flat top domed piston) to then put a smaller carb on the engine?  Just doesnt make sense...

Echo has even gone as far as to sanitize their IPL;s, removing references to the HDA-45 or HDA-63 carbs as having been used on the 8000.  Take a look at the factory diagrams if you dont believe me.  Its only through Walbro that the references to these larger carbs are available.
