I've got a 10-10 from about 1980 I think is the year. A couple of weekends ago I dragged the family out to help me cut some fire wood. I usually take a couple of chainsaws in case I hit a rock, pinch a saw or some other stupid trick. After sawing with one of my fine Stihl chainsaws, I put the ear plugs-in and cranked the McCulloch. My wife and kids had never heard that saw run before and it was a blast seeing their reaction to it. It cut GREAT, but you are right - pound for pound, it's got to be the loudest chainsaw out there. On our day out, there was no question it was a chainsaw in the woods, not a weedeater.
BTW, saw has an 18 inch bar, spikes and I was bucking up an old dead oak that was about 22 inches in diameter. I'd bury the saw and it would lug right through the wood.
Great saw!
