Disconnect the fuel line at carb and run a Vac test on the fuel tank. If it holds vac the valve is bad, I had a Stihl 046 drive me insane trying to find out why it was doing the same thing. Not saying this is the problem you are having but if the valve is bad it won't allow fuel to get to the carb and you run lean. In your case you have a pressure/vac tester but if you don't an easy way to find out is start the saw and turn it on it's side like you are filling the tank and loosen the fuel cap (doing this with a half a tank of fuel) and if the saw continues to run then tighten the fuel cap and see if it dies.
