Echo CS-670PP

[TonyM]

Well I've finally gotten some time on the Echo 670 that Dozer Dan ported for me. I was cutting some 14-16" black cherry today and counting roughly in my head. I'd say it's somewhere around 6 secs. This saw started out about 80-85% as fast as my 372XP, and it's certainly faster than the 372 now. I haven't taken the time to do some bar & chain swapping between the two and timing with a watch, but I will soon. It sure is fun to bury that saw in a log and watch the chips fly. I'm thinking about having Ken Dunn do the Solo 651 next. Only problem is I've been using it so often in this mess of downed trees I've been cutting into firewood, I hate to part with it right now. The Echo is not much fun to use above waist high for very long. Hmmm, if I could just get someone to lend me one of their Dan Henry 346XPs for awhile

Tony, it's neat to hear about power porting your echo 670 because I got one too. This past summer Danny opened up the muffler on mine and this saw does all I need a saw to do. I even milled some red oak with it. I haven't put anything longer than a 20" bar on it though. Please keep me (us) posted on your experiments/comparisons with the 670--I'm really interested. thanks bob.

ps. Dan is sure a super person.

Tony where is Hastings Michigan?? I happen to live in Grand Blanc which is near Flint. Has ur Echo given u any problems? How do u like it.
Also, for any Michiganians that read this, do u know of any Dolmar Dealers in South East Michigan....??

 

[TonyM]

Hastings is on the west side, between Grand Rapids and Battle Creek. I'm fairly familiar with Flint as I went to college (GMI) there.

The Echo has been a fine saw. Not up to the power to displacement or power to weight of the higher end Stihls and Husqvarnas (that is of course until Dan was finished with it), but a good value for the cost conscious.

I know of a Dolmar dealer in Vermontville, and in Grand Haven, but that doesn't help you much.

Finally timed the echo cs670PP and 372xp w/ the same bar and chain, and I'm a little disappointed. I really thought the echo felt faster, but it's not so. In a 10" dia black locust, the 670 averaged 4.8 sec, and the 372 averaged 4.7 sec. It's an improvement over stock by about 20%. I may do further tests.

Thanks for the info Tony.

It looks like the PP670 is cutting about the same times as a stock 372. Is a stock 670 only 20% slower then a stock 372?
I wish that Echo would make a saw in-between the 670 and the 8000. They could use a 75cc saw in there line up.

Dan, Perhaps you`ve forgotten the CS750EVL, reliable as a stone but heavier than a dead minister. I think that Echo likes to overbuild for the long haul at the expense of weight and output power. They were a good saw in their day.

All the cuts I timed before mods had the Echo between 80-85% as fast as the 372.

So what saw do you LIKE better?

Hmm, that's kind of like what do I like better, ice cream or candy? Obviously the 372 gets there with less $$$$ over all, but the echo has a nice feel (balance) to it. 372 is smoother and has the outboard sprocket. Echo starts nicely and is different than the norm.

I have a friend that runs a 670 it runs well but their is no way HIS runs 80-85% slower than a stock 372. I would say maybe like 70-75% slower than a 372 on a good day. Tony you must either have a extremely good 670 or a real bad 372.

I recently bought 2 new saws, they are the very same model. Even though they are the same one is clearly stronger then the other. I have adjusted the carb on the weaker saw but cant get it to run as strong as the other. Dont get me wrong they both run good one is just stronger. I have seen this to be true in some bikes as well as cars. Once in a while it is possible to get something that excells in its own class.

 

[TonyM]

I had to remove the carb adjustment limiters in order to really get the saw to run. It was set way lean from the factory. I also opened the muffler up very slightly. In that condition it was about 80% as fast as the 372. My 372 runs fine. I've had it since new.

 

[eric_271]

what is the hp on your 670?

 

[eric_271]

Imean what is the factory hp on your 670?

 

[TonyM]

Echo USA doesn't publish Hp figures. My best guess from looking at international sites is 4.3-4.4 Hp. As it happens 5.4 Hp (372)* .8 = 4.32 Hp.

 

[eric_271]

I have a 670 super jonsered.Thats not the same saw as your echo 670 is it?

 

[Doug01]

The Echo's are made in Japan I believe. The Jonsey should be a Sweed product. Not the same saws.
