First off, what a great/informative site on chainsaws! I really enjoy being in the woods either making firewood, or getting logs ready for the sawmill at my inlaws farm. I've had a couple of Stihl saws, and my current one is an 066 mag. (non redlight) with the basic muffler mod, and the "correct" dual port magnum muffler. I'm also running a 20" sprocket nose bar. I bought this saw used from a great place that used to be in Alma, WI in about '97, and have not had a single issue with the saw. I also like to split wood for the boiler. Such a great workout and sense of accomplishment at the same time. For splitting, I'm using a Fiskars axe their biggest one - don't remember the model. Super efficient head for splitting all types of wood, but the handle is wayyyyyyyyyyyy too short - just got to be careful, that's all. It would be great to find a place down here to help someone make some wood. I will say, what a night and day difference when I did the muffler mod. Everyone here knows this, but it's amazing - frozen white oak is now butter...
