I broke in a new MS361 last month for a non profit org that they will be using primarily on the 'fire line' fighting forest fires. And everything with it has gone according to the book; a fabulous saw. However, due to the break in process, I never ran it at max rpm in a cut, although its ready for that now.
Purpose of this query, is I've now bought a 'used' MS361 for my own personal use cutting firewood. I made the muffler mod of extra holes.
But, now I've got what may or may not be a problem, a sudden high accelleration in the cut. On two separate occasions, it sounded almost like it was running out of fuel, etc. but that is not the case, and it stops the higher accelleration when I push it down harder into the cut. As I said, this has happened on two different occasions; and, it may be that the dead oak wood is so hard that the full chisel chain is jumping up out of the cut and causing it to accellerate.
Current carb setting is 3/4 out on the H and 1/4 out on the L. Recommended settings. I have not removed the carb and blown it out or checked the lever setting. Which I can do; but, have not done as yet.
I don't know how high the rpms are supposed to be on the MS361, as I'm more accustomed to the 026/260 and 360/Pro sounds and performance. Based on what I've been reading on this site; it may just be a 'hotter' saw than I'm used to. But, I don't want to 'burn it up' either.
I don't have a tach; but, I can borrow one if necessary.
Am I over reacting or is there a concern here? Your Ideas and comments are welcome.
