I was gonna try a 16'' bar see how I would like that combination. but so far not very impressed with this saw. first few times I went to cut it was fine. seems like as soon as the chain would throw just a tad bit of dust it was all gunked up around the oiling hole etc. cleaned everything. The guide bar. around the sprocket etc, put it back together, had a light mist of oil on some cardboard. Figured it was good to go. Got cutting. 2 min in, check to see if it was still oiling and nothing.
I've read these ms250's have problems oiling. the oiling hole on the bar is tiny. once again, took bar and chain off, cleaned bar, ran screw driver down guide bar, blew everything out around sprocket etc. and same thing. It's like if the chain isn't perfectly sharp the oiling assembly slings oil everywhere but the bar and dust just caked up in there. I've ran other saws, and never had that problem. echo 440evl, various poulans etc, never had that happen, even if the chain was partially dull. You could get through whatever you were cutting deep in the brush without stopping every two minutes to clean out the bar etc. I'm not the best at sharpening so I didn't really wanna booger up this brand new chain. really only have around 1.5 hrs total run time on it. didn't hit any rocks, never put it in the dirt.
It's just tree tops from logging. chain is just throwing a tad bit of dust. definitely no pro at this, just cut occasional firewood. guess i'll run a file over it. maybe put a new chain on.
Have the two year warranty but i know if I take it back, they see oil coming off the chain, they won't do anything. I'm just using regular 30 wt bar oil. I'll file chain, see if that helps, maybe try a different bar oil, then maybe just open up the bar oiling hole a bit.
