Opinions on Echo CS-670

[TonyM]

I've often thought I'd like to try running a newer Echo to see how they stack up against Husqvarna and Stihl. I picked up a new Echo CS-670 on ebay for $385 thinking that for that price even a slightly slower 67cc saw would be okay. I've found several different power ratings for the CS-670/CS-6701 depending on what country's website I look at, ranging from 3.17kW to 4.35kW. I assume that the differences come from varying emission standards. The US Echo website does not publish power specifications, probably because they do not compare well to Husqvarna and Stihl, but it does claim 14,000 no load RPM's. So, does anyone have an opinion on the CS-670, and with muffler mods, does anyone think the 4.35kW is possible (Seems high to me)?

Does anyone know the translation to Amurikan standards? This Southern redneck has no idea what kW means....

Limited experience with the 670. The one I used had already been drug through the grinder (commercial tree crew, 1 year old) and wasn't highly regarded by anyone on the crew. But that can happen with any saw that is never set up right from the get go, and this one had a troublesome carb to say the least. More than likely from neglect/ improper settings/ getting 'fixed' by a crew member.
I've had excellent service from the lil 3400's for climbing, and Echo has always made solid engines for the most part. Price would have to be real good for me to buy one of the 670's though.

I ran an echo 8000 (80cc) for a few years on the big stuff. Tons of torque, but a little slow. Engines are bulletproof, simple filter
that needs to be cleaned often. Good saw, not a fast saw.

1 hp = 745.7 W
1000 W (1 kW) = 1.34 hp

3170 W = 4.25 hp
4350 W = 5.8 hp

W meaning Watt. kW meaning kilowatt. Confusing because its usually used in electricity, but what it is is a measure of force or something like that.
