So today I had just a bit of time and got the CS-8000 going a bit. I "noodled" about 5 silver maple hardwood logs, about 5-8 feet long and about 10-12" diameter. I just dug it in and did a vertical cut through the center of each, continuing the cut line from one end to the other. I have fun noodling and no setup at all. These had been drying about 6 months already since last fall so needed to get the drying process started on them as cut slabs. I'm not sure yet what I'll do with them, so I just put one cut through the Pith in the middle. My old new to me Gray saw is not tuned up right and it wanted to die on me a few times coming off idle. Didn't want to restart easily either when I was done. The bar I used was a 24" with a new chain but not a milling chain at all. Stock saw and with the older lower compression ratio piston/cylinder in this one. It impressed me a good bit. I could get the one pass through the 8 foot long log in about 4 minutes. Not really struggling in any way and pretty much full chain speed all the way through, even though it is not tuned at all right now. If anything, I slowed it down a few times to be sure my cutting line was straight. I think tuned and with muffler mod and a milling chain on it, I ought to about cut the 4 minutes in half to 2 minutes or so per pass. My CS-590 can do this one pass in about twice this time or around 8 minutes, with milling chain, stock saw. So it is about twice as fast limping along as the CS-590 for milling, 80.7 cc vs 60 cc saws, but about 27 years of technology and age between them. The 8000 is not a light saw if that is a factor. For milling not much of a factor for me. The newer 800p orange ones are going to have a much better piston/chamber and also better porting than my old one. I want to say should do fine milling with one and ought to hold its own against any 80 cc class saw, although only timed tests would say for sure. I'm real glad I got mine used and hope to use it for next 25 years or so if I can. I'll have to leave the 800p comparisons to others as mine is the older style. Only negative I can think of with these is no decompression valve for starting on any of them. The 590 has that, as did my old Pro Macs, and I don't know why Echo didn't include that on them. Even the new 800p's don't have one. So starting is a tough pull, but normally it is only two pulls on all the Echo's I've used, one full out choke and one normal choke after that. - Paul
