Hi guys, my friend Bob passed away and his family is selling his stuff. They found a KD-3 #104290 in it's own custom box. The motor is well used but fairly clean. It turns over with ease, the throttle slides easily and nothing is seized. The decals are fried but it has the original rope. The prop is perfect. Bob was meticulous in taking care of his mechanical stuff, I know I could get this running in a couple hours with the right parts. What should I offer?
