I don't know. I'm a small buisnes man myself and if the deal was in writing,fax,email ect. 1/2 down 1/2 recieved (which I do quite often) send the piece cod and if he refuses the shipment that's breach of contract then keep his down payment until engine can be sold for amount agreed and refund him. If he pays win win for all. Just my opinion but honest buisnes means keeping your word no matter how much it hurts.
