Stihl Wrenching
You have tank pressure anytime you agitate the fuel, or if it gets warmer then the surroundings, etc... Pressure is GOOD... it help starting as you don't have to do much sucking of gas from the tank. Put your orange flapper back - it's a good thing... and you need it with your style of vent to stop leakage from the tank.
As for your carb... pressure test it... you either have a bad seat (unlikely), a bad needle (maybe), your metering spring is not located in the metering arm divit, or the metering arm is hopelessly out of adustment. Do you have the carb gaskets in the correct order - maybe someone screwed with the carb?
Have you tried your old 403 carb back on the saw to see if it runs fine?
Sorry... no more WT194's. but you can get one from your Walbro dealer brand new for $43 list
