Hi guys, I know its likely a piece of crap saw in alot of your eyes but I just purchased a brand new MS 390 last week. I opted for this one over the MS361 just because of the $250 price difference and the 390 will do more than anything I have to do as I only cut for my dad and myself. Question, during the break in period how should I run it and for how long? I'll be using Sunoco Ultra 94 gas with the Stihl 2 stroke oil. It says in the manual not to run it WOT without load in which I wouldn't anyways but can I run it WOT when processing wood? What are your guys thoughts on the saw? I got it with a 20" bar and 2 loops for $590 CDN which is around $500 USD. Opinions, thoughts are greatly appreciated. Thanks again.
