    My big saw is the 8000 I have been running it for 15 years.. I'm wanting a new "big saw" but this one won't quit.. I've logged with it, milled with it.. And cut my firewood with it .. I also have the 670.. Same age as the 8000... They both just keep on trucking...

    I must say I am disappointed in the 6700 in the cut. I always said it felt like a husky 365 down on power in the cut. But the wood would never know the difference.
    I thought I could get alittle more with muffler mod and putting a 8000 carb on it. It felt better in the cut. I also put the side tensioner 670 clutch cover and brake set up on it.
    Then I ran my poulan 415. Nuff said I pulled the 8000 carb back off. Stock porting just isnt there on the 6700. Sort of reminds me of the poulan 3800 in the cuts.

    6700 up for trade PHO or b+c can be worked out for ?

    Same chain for all 3 in dry harden ash.

    Got to unbox the saw today. My first impression: This thing is built like a tank...it's nearly all metal! Weighed 16.5 lb. out of the box which matched the specs. Compression out of the box was 145 psi. (that's gonna get bumped up:)). Muff is typical Echo...very stuffed up (that will change also).

    WoooHooo about time. I look forward to all your info on it. It is on my list as a possible future milling saw.

    Sure looks like an 8000 with bng (bold new graphics). The muffler is a little different.

    Nice, enjoy. Big saws are fun to run especially after some mods. What size bar are you gonna run on it.

    Thanks for your help with this (in our PM's). It appears that the 800p has a smaller carb than the 8000. Will be interesting to see, after it is ported, if the carb is a limiting factor. We will find out in March (@Mastermind).

    It came with a 36" but we won't use that very often. Will be nice to have it when the need arises though. This saw will probably see the majority of it's action with a 28" bar.

    Randy's done a great job on this saw but, as mentioned above, the carb is too small. He would like to put a bigger carb on it but it doesn't sound like there are many good options. I'm under the impression that with a bigger carb, there's power yet to be gained in this saw.

    JJ-

    All saws are different and sawyers tune them differently but... your 6700 doesn't sound like its revving full song. my cs 670 is tuned to a max unloaded 13k rpm and a little rich on the L side and has good power. i suspect i could push that to 13.5k but i'm conservative by nature. most important it will hold its max torque rpm in the cut like a dog on a bone. i can keep the depth gauges low and lean on the spikes and it loves it. true, the big echos are not hotrods like their husky equivalents and don't sound as angry but they might produce more torque and do a little more in a days work. And they will last a long time.

    i'm still unclear on the differences between the 680, 670 and 6700 and whether it would be smart to replace a worn out top end with the new quad port ones or if that's even possible. i'm skeptical.

    Earlier comments by Chris R aren't too accurate in my opinion. My guess is that he prefers the more modern peakier, narrow power bands and higher rpms of the huskys. nothing wrong with that.

    I don't need to state the obvious but just to CMA: Ported vs. Ported, the 800p (80.7 cc) and the 661 (91.1 cc) are in different classes. But let's look at where Randy is with the 800p at this time. Just like Kevin suspected back in December, the 800p has a small carb and it's preventing it from being stronger. But even with an undersized carb, it being Randy's first go at the 800p, it being 10.4 cc smaller than the 661, and the fact that it's an echo (lol)...I think this saw is running damn good. It's hard to tell exactly but it looks like the 800p is running about 6 seconds slower than the ported "new recipe" 661 in the same log:




    I may be wrong on this but if it's true that a "hamstrung" ported 800p is running that close to the ported 661, I think that's impressive. How would it run against a stock 661? And how would it run against a stock or ported 661 if it had a bigger carb? It might be closer than we think.

    interesting vids but the real questions, from the pov of crew trying to make a few bucks, are how fast will the truck get full, when can we move on to the next job and is this piece-a-crap going to break again? i've never worked with a 661 but have many hours, both working with and repairing, (stock) 066's, the reason i switched to a 394. i wonder if the echo 800's have smaller carbs than the echo 8000's. i've never measured one but the 8000's look pretty beefy. i wish more guys used the echos. then maybe we'd know the difference between models of the same displacement i.e. 670 vs 6700 and 800 vs. 8000. also, made me chuckle to see the husky bar instead of a d176 on the echo. better call jon1212.

    @Idahonative Why did you port a 600 instead of your 620? Just curious

    Rock on my friend:rock:

    What is holding you back from throwing on a big carb?
