I am working at converting a 625 to a 670 at the moment. It's in about the same condition as yours cosmetically, but bearings are good and I'll put seals in it while I'm at it. Should be a good cheap firewood saw.
I like this pic because i learned something. Long story short i bought a 181/288 and it had the J-red west coast intake on it. I didnt know thats what it was tho, figured it was an a/m thing. Now its on my 630 where it belongs.20” 404![]()
