Don't know much about this engine. It was my grandfather's engine that he had in his crop duster I know it was almost new when he took it out and it has been sitting on an engine stand. It will need to be probably gone through but should be all good parts there was nothing wrong with it as far as we know when he sold his plane. He is now gone so We are not able to ask him questions about it and I do not know much about it. The engine is being sold as is.
