I rebuilt the starter with a kit off of ebay and it turned the ski over one time. It will crank with the plugs out but not in. Tried to jump with non running vehichle just wont turn over and starter gets hot. I just figured a new starter would fix it but I don't want to burn up another if it isn't the problem. I have fully charged battery, cleaned all grounds and greased them with di electric so it there something else?
