JRED 670

[Keltic]

Hi, was offered a rebuilt 670, interested in experiences/ opinions of this saw. Thanks FMK

If you get one pinched in a cut don't pull to hard or you'll break the rubber mount between the intake and the carb.  That's the only experience I've ever had with one but it ran well and cut good until I got it pinched.  The guy I was working for took it back to the dealer and I never saw it again.

I have one of these 670s myself, I LOVE it, just gotta get it to run soon. But it is basically a Husky 266 with Jonsered decals on it. They are lighter than my McCulloch PM610 which is a 3.7 CID and weighs about 20 LBS or so, while the 670 is 13.6LBS and very nice. I cant complain about their style. But in short the 670 is a VERY GOOD saw.
