Hi, I don't know much about motors but I do know an important thing to check with an unknown motor is if the piston is free and it is. I was going to try to learn how to get it running but I just don't have time. The parts in the picture were and are still in separate bags. I have no idea the condition of it so it is being sold as-is. I also have a couple larger props for sale so if you are interested in seeing those pleases ask before you come so I can have them out to show you.
