hi Leon I have been watching your videos for a few months now, and i am impressed with your knowledge and skill, dealing with these old chainsaws. I have a 1968 Homelite xl 102 automatic. I replaced the fuel line, and put a carb kit in it. It now runs on 44 to 1 stihl ultra and non ethinol gas. The saw runs strong, however i am woried about the fuel tank vent as per your video on the saw. Cant find a replacement duckbill for it and i am not on pay pal. Is there a different vent i could screw into the tank. Appreciate your advice. Carl
