When our friends were here from Washington, the Daddy spent a whole day working with our son on restoring this four wheeler to working condition. He also gave a great science lesson on combustion and how an engine works. We couldn't hardly believe that they got this machine to work! Someone had brought it over as a project for our son to work on and he'd been looking forward to this visit and working with his best friends Dad on this very project. He was one happy boy to have spent precious time in this way!
