vent

After pulling my hair out trying o get this saw to run, I think I found the problem. It is hard to prime, the button is stiff when pressed, even though its new, and the return line will not allow air to pass thru it. I accidently discovered the vent plug between the handle and tank on the right...

I got an old Husky 162 SE and I only have one problem with it, the fuel tank cap is the old style with a rubber check valve in it that lets air in but keeps the fuel from dribbling out. Well, the rubber seal is broken and so I need a new cap, unfortunately the vented caps don't exist any more...
