Sorry for your loss. Lost my grandma a few years back, amazing woman and fantastic link to the past, grew up in the tenements, lived through the Great Depression, had a career, went back to school in her 50s and had another career. They don’t make them like they used to. I’d run some fresh fuel in that beast and change the fuel filter as well as drop some Techron into the tank. Rattle can or wrap for the roof. Check the brake lines as well.
