I have and almost new Stihl MS290 (about 8 months old). The chain oiler oils the chain as it should, and it seems that I have it set right, as upon an empty gas tank, there is usually about 1/4 tank of oil left. The problem is that not only does it oil the chain, it oils the clutch and the inside of the engine housing too. I pulled the clutch, cleaned everything up really good, put it back together and ran it at half throttle for a minute or so. Opened it back up, and everything was oil soaked again. It even drips from the hole in the bottom where the oiler adjuster screw is, and it drips from the engine pan mounting bolt holes. There's so much oil that I cant tell where it's leaking from. It doesnt leak at all if it's not run, so I'm sure its not the tank. I would be greatful for any suggestions, and hopefully I can resolve this without returning the saw for warranty repairs
