Stihl 010 AV
I have rebuilt this saw and noticed that there is an additional hole next to where the gas line goes into the tank. I believe that it is a vent hole but never noticed it before and gas leaks out of it when the saw is in use. Does anyone know if there is a special fitting for this? I don't remember removing one. Does anyone know where I can obtain a download that would show a parts diagram for this saw? Thank you.
