    Let me know how that works for ya swampy.......I looked for a good video link on tuning but most of them were filmed by some really screwy people. If I find a good video I'll make sure I send it your way.

    Will do SO. I was just reading the 660 manual it says the hi rpm's should be set at 9500, the low idle at 2500.

    Take those specs with a grain of salt Zap. I'd take some baseline numbers before you change anything. Adjust to spec, but if the saw still doesn't sound/run right, don't be afraid to tune "outside the box" a little.

    a big +1 to that, MM. Swampy, those factory specs are a baseline. Altitude, temp and humidity, etc. play a factor in tuning as well. Don't be afraid to let your ear do some of the tuning. You'll get it figured out. We'll be here for support.
