I have several good old Homelite chainsaws from the '70's and 80's. One thing they seem to have in common is the challenge with fuel cap ventilation. I don't know if I've ever had one with an exception. When you tilt the saw to fall a tree gas runs out the vent hole in the cap (with a full tank it just guzzles on some of them). Back in the day when they were close to new I bought a new fuel cap and it still did the same thing. Has anyone come up with a solution that works? Is there any other type of aftermarket cap available that would replace the original and not leak? I would appreciate to hear thoughts and experience, thanks.
