Hi All- I'm a bit of a lurker, but I am going to de-lurk and ask a question. So, I've graduated to tuning with a tach. It SEEMS the easiest base way of tuning with a tach is gett'er running near what feels good, then double check, and do again. BUT, it seems the extremes are pretty set in stone (on stock-ish saws). Aim for an idle of 2700s and then "book" value for max, outta wood... SO, my question is, what is the right 3 second max out of wood for the following: 200t Muff modded 361 Dual port muff 660 and since I'm asking ht131 Thank you in advance, WL re-lurk.
