I can supply manuals & parts for many Iseki models from US sources . The TS 2 cylinder models require ordering from Japan. Although I have been able to find some of the parts for them from US sources. I know when Bolens was still going, I was able to sell parts for less than what they were charging. sheaftractor@coiinc.com
Try Rainbow distributors. They have a guy named Derrick who seems to know what he's talking about. They're in Hawaii and get their parts from Japan. Dealt with them before and am trying to do so again.
