It can, some modules get their timing advance curve screwed up so they wont rev but still have great spark.
How old is you fuel mix?

if you want it fixed i live an hour from you.
Well if its getting fuel, spark and compression it should run. Two last things: timing is off or compression is below 120#. Check the tightness of the flywheel nut. How long ago did the saw last run and how did it run and start? OHH how is your spark arrestor in the muffler, it should be clean...
How sure are you about the tune? Sounds like you may be running it too lean and have scored the piston/cylinder. Did you pull the muffler and look inside the P/C? I think you should do that FIRST.
i happen to have an xpw piston and rings
