Good info guys. I bought the saw above and it looks to be in good shape! Haven't had time to start it up yet but happy about this deal. Now that I have it, if anyone had a parts saw pro mac 650, very cheap, or key parts that go bad, do let me know as that would be nice to have sometime. I already have a pro mac 555 smaller cc one not running great yet, so can share bar/chains with it.
I've been using my little 42 cc Poulan for milling so far!! Yes, it can be slow, but it can go through 12" wide boards! Most of its use was 6-8" wide but up to 6 feet long. With a good well cut milling chain on it, and muffler mod on it, that I now know how to do thanks to this site, it can do suprisingly well. I suspect this higher horsepower 610 in the 650 will do a good deal better than that, even if speed is less than the newer Poulan, torque is much higher with the promac. I'll probably keep one chain for milling and one for normal tree cutting between the two pro macs I have once I get it all running good. I'll give it a go with the milling. If I need more, may still get a different saw later on for milling. No worries! My milling is top down mini-mill and hobbyist woodworker use only, so occasional. I find it really fun to do though and very addictive! So far, some Dogwood (really nice stuff), Hawthorne (super hard and dense wood), Spalted Ash, Silver Maple, and a rare Plum tree, all milled with my little 42 cc Poulan! (Did take a while). I'm loving this website AND the people in it. Great guys here like the OP of this deal. Many thanks! - Paul
