I cut all my wood last year (first year burning was last year) and this year so far with my stihl ms170 with a 16" bar. Actually a really good running saw and ive cut alot of trees down that were way to big for that saw. I posted a video last week in the saw section and a few people told me i how dumb i was for using such a small saw on a tree so big.
Finally after reading a few posts and doing some research over the last week, i decided i was getting a new saw. It came down to 2 saws, either a ms250 or a ms290. I knew i wanted as light as possible and after talking with my neighbor who has the ms290,so on saturday i bought a brand new ms250 with 18" bar.
Wow what a huge differance from the ms170! I feel like i need to be alot more carefull now with this saw. Alot more power than my little 170! So far im lovin this 250 and i found the more i cut with it, the more power it seems to get. I have only ran 4 tanks so far and they say 5 to 15 is the breakin period. Looks like ill be keeping the 170 and 16" bar as a second saw for limbs etc. since it gets really good gas mileage.
