I tested my newest creation in wood today, an Asian Blue 660 w/066 jug on it. I'm pleased with how it ran. I also tested myself a bit, not that I did that much, but first time I cut wood since I pinched a nerve in my back 3+ weeks ago. My PT guy gave it the OK. I did a thread on the build in the Asian saw section.
Was only Red Maple, but the 28" bar barely poked through it. If you really leaned on it you could slow it down, but it kept chugging. I like that in a large saw as I often use them for milling or stumping. The saw started easily, idled smoothly, ran strong, and restarted with the decomp (when warm) very easily. My back appreciated that today!
In addition, my Mustang likes the color!
