I think that I am missing one of the two large springs, if there are two the book says it does. The book only mentions the 3 small check barings, so what about the large ball and is there supose to be a larg ball bering with the 2nd large spring? Where do these 6 brass washers go? The manual says that they are 3 in each hole but I found them with the one large spring. Is there a part # for them, where can I get them? Please help me!!!
