You should be able to. If the teeth on the starter are stripped then there is no reason for it to be binding thus stopping the motor from moving. I would investigate further. If your interested in a project that is. Sounds like the cylinder is siezed. Doesn't mean its a total loss tho. A good machine shop can get the piston out and bore the cylinder and you could be in business. But I am the guy who never throws anything away because I still think there's hope fore it. Jut ask my wife about the yard full of projects.
