I'm jealous, some guys just have all the luck in finding saws. This is the latest addition to my clutch of Mac's. A 450 that has the Mac carb in it that I was able to get working and you can sure tell it has one in it too. There is plenty of power with this saw, I have used it the woodpile a couple weekends this last month, hard to stop this one, going to run it against one of my Sthils if I can find a volunteer some weekend.
