Hi, folks... I'm going to be visiting my parents for Thanksgiving, and I'm thinking about replacing the fuel tank on my dad's 026 for him. He's fixed it with J-B weld several times; the fix lasts for a while and then comes apart. Anyway, I was thinking about getting a used tank/handle assembly either from a member here or off of Ebay. Are there any tips/tricks involved? Is this a tough job? What about compatibility issues? The only one that comes to my mind is fuel vent designs... I think Dad might have a "red lever" saw with the tall black fuel vent.
