After running good day before, one day my saw wont even puff. After diagnosing my problem, I have noticed that no fuel is pulled from carb into cylinder. Compression was good but vacuum test failed, so I narrowed it down to faulty crank seals. Saw uses vacuum created in crankcase to pump fuel through carburator. Without vacuum there is no fuel to the cylinder.
