Probably worthwhile having Cole Haugh go through it. He used to do the warranty work for Aspen Outfitting and has done several jobs for me, all to my complete satisfaction. He can check the internal parts for hardness and correct if necessary. He also has a good supply of Ugartechea spare parts, or used to at least.
