Husqvarna 3120 fuel tank vent

Where is the fuel tank vent located on these saws? I do not see anything on the parts list that looks like a vent.

Today while cutting I had both my 3120s fail to start after running a while. On each saw when I opened the fuel cap I noticed a slight vacuum. I could get them to run but only briefly. This happened after both saws were hot and had run several tanks of gas with no problems.

I need to use them tomorrow and the rest of this week so I need to fix this myself. There is not a decent saw shop anywhere around here.

Can I gently pressurize the tank and back flush the vent? Do I need to take the saw apart to get to the vent or vent hose? Where is it? On my other saws I can see the vent - not on these.

I bet someone over on the CS forum would know or have run into that before man. Alot of super-technical guys over there

OK, found it. The vent exits under the upper housing in the seam by the tank and the rear AV mount. ---Very--- dirty place for a breather. My other saws exit into the upper cover by the carb.

I'll have to check mine and see if they're in the same place.
