RJ has it right on the oil adjustment screw. 3-4 years ago I bought a new 029 (same as yours). Burned one tank of gas and only used 1/2 tank of chain oil with the flow wide open. Took it to the dealer and got it back in a couple days. Same thing, back to the dealer. And again and again. Put it on a shelf in the shop figuring I'll work on it later. Two months ago my old 360 burped. Break out the Stihl, buy a service manual, tear it down, put in a new pump, a new pickup strainer & tube, check for obstructions, the whole smear right to the letter per the service manual. Back together, run it with bar off, pumps oil like mad. Ran a tank of gas, used almost a whole tank of oil. Hooray, I fixed it. Same day, two tanks later back to original 1/2 tank problem, bar & chain overheating. By now I have about $500 into this saw and at the outside 10 hours of use. I threw it as far as I could down the hill (wasn't far I admit but not bad for an old geezer) went back to my shop and spent an hour fixing the old Homelite 360 and finished cutting my winter fire wood. That 029 is still laying down there and I keep thinking next time I am down there with the backhoe I'll give it a decent burial. Maybe next year..... .. Perhaps I just got a bad one. Good luck with yours. Joe
