Is a husquvarna 136 fuel tank suppose to be pressurized or is it vented? I know the tank has a check valve so im not sure how that works, the saw will crank and idle but dies when you give it gas. i bought new carb off ebay instead of cleaning the old one and when i pulled the fuel line off it sprayed all the gas out of the tank so my guess is its supposed to be vented i know stihl saws are vented but all i see is check valve for this saw so is that the vent?
