Ran a 290 last night with a 20in. bar full chisel no skip on the saw buck last night.(cold night for sure) Friend of mine had to have this saw running good for today. Tune it sharpen the 3 chains and made some cookies. This is the 2nd 290 I have done in the last 2 weeks with this set up. imo this is a very good saw with carb adjustment always thought they would be under powered for a 20 in. bar there not. Running strong on the saw buck! and this one was a 3/8 set up.Its a lot funnier to get someone else ready to go out in sub weather than myself.lol
