My husqvarna 350 seems to be starving for fuel, I've been told to clean the tank vent, and that still dosen't work, I've even run the saw without the vent filter in and it still acts like it runs out of gas. You can open the tank, and re-prime it and it will run just long enough to empty the fuel bowl and line and then it starves for fuel again..... any suggestions?

lack of fuel is probably the problem
where from is the question
taking that it is a lawn mower ( husqvarna make a wide range if machinery)
check the hose and filter at the end of the hose at the tank ( inside)
check that there is fuel flowing through the fuel tap as the aluminium type taps corrode inside and block off the fuel
check that there is fuel flowing through the needle and seat when the bowl is removed
check the main jet for blockage
when you refer to using it i take that as your motor is running properly which rules out the fuel supply lines, and the primer bulb .. probaly one of two things check the gas cap and make sure it has a washer and makes a liquid tight seal and inspect the tanke for any hairline cracks that begin to drip when the motor is at idle, if it could also b the primer return line that vents back to the tank ethanol has a bad habit of eating up fuel lines on two cycles
This sounds like fuel starvation, replace the fuel filter in the fuel tank, if this does not help, when it starts to die just slacken off the fuel filler cap, if it picks up and runs normaly then it is a tank braeather issue, the breather is on the top right hand corner of the fuel tank, replace it.
I would carefully remove gas cap and clean with mild soap and hot water using tooth brush to clean dirt and dust from both sides of cap. If possible blow out with air and mak sure it is thorgouhly dry before you put it back on your saw. If this does'nt help I would try anew cap. Hope this helps. Thanks
Check the fuel tank vent for plugging. Make sure the carburetor is securely fastened at all points. Be sure to use fresh fuel/oil mix (50:1) and shake the container thoroughly each time just before adding to tank to prevent oil starvation. Check the muffler for plugging. It's possible that the diaphragm in the lower chamber of the carburetor has failed--it should be flexible with no holes or cracks. Hope some of this helps!
I think your on the right track Blowing compressed air through your tank vent is great but it is way more air than the natural asperation that the saw pulls on it own I would replace the vent cap and also look for a pinched fuel line between the fuel tank and the carb
My 372 xp did that and when I talked to the repair shop they even showed me. There is a fiberglass gasket that is used to mount the carburetor to the engine. I have no idea on how this happens, but I saw it with my own eyes. The gasket had actually folded over. They replaced it with a rubber one and have had no problem since. The saw was hard to start, would run as long as I didn't try to cut anything and when I did it would open up and then die. I could be giving wrong information, but that sounds exactly like the problem I was having.
