Have been given a Stihl MS170 as a non runner. Stripped and cleaned carb and it now fires easily and runs up okay except for excessive smoke which smells like the crankcase is ingesting bar oil somehow. Is this possible?.
It ran up perfectly after I serviced it but then after filling up the bar oil reservoir it's burning acrid smoke. Will empty the bar oil tank to verify the idea that it's leaking either onto the exhaust or into the crankcase by some means.Did you flush the fuel system? Maybe the muffler is full of some kind of solvent? Did you check the screen?
