Well the 260 Pro I had did what it was req'd to do , which was limbing for almost 5 yrs . The MS-361 did most of the felling and bucking. I skipped over the MS-360. model , which again was a leaning running unit . The MS-660 I purchased was the only Stihl I had that did not require re- jetting , it started and ran fine from the get go. I did however Muffler mod all my Stihls eventually . The local Stihl Dealer went to Husquarna & Echo , so eventually I sold off all the Stihl, s . Not really sold on the new computerized saws at least until they get all the bugs out . My Buddy sold his 261 after 2-3 yrs and purchased 2 Echos CS-400 & CS-600. No problems over almost 8 yrs . A other friend of mine has a Stihl CM had it reflashed within a mth of purchase , has been fine since .
I have one more saw to collect , since I just sold my 543 xp which my daughter primarily used . Leaning toward either another Husky or J-Red or even another Dolkita ..Time will tell ! lol.
