Com :Cliff : Chainsaw sharpener is sharpening the WRONG side of the chain.
And it's not hitting the rakes, which is generally step 1 when it's needed.
Hardware stores often have a device that clamps onto the bar and holds a round file at a fixed angle of your choosing.
About $30. Use the proper sized round file that fits your tooth size, hit the rakes with a flat file 1 stroke each every other sharpening.
Done properly, you don't have sawdust, you have chips.
