Having fun with this saw. Appears the breather tube on the gas tank is blowing gas out the end at WOT. View attachment 290926 That is the end of the tube above to the right side of the plug. Below where it comes out of the gas tank View attachment 290927 . I have Google'g this one too. No joy. I am not entirely sure that this is the original tube? My dad may have replaced it a while ago. Any idea's what is causing this?
