610
Yeah, both saws are 610 PMs. They run good for big-brother hand-me-downs. He cut fire wood in California (almond and other orchard wood) with them for years. He gave them to me in 2004. I keep them running with parts from all over.
I found a guy back east (retired and drives a school bus) that sold me some oil pumps etc. The parts are hard to find.
I rotated them on the oak between tanks to keep em cool. I would have liked to have a 361 with a 30" bar like my neighbor offered but I like using my "own two feet".
I have a cheap bench grinder set at 23 degrees. I went through two chains a day. I lost @ ten pounds off my waist (excess fat).
I felt like that gregory peck strapped to "Moby- :censored:" when I was standing on top. All in a pile now.
