It has a context to fit into Ty: the Japanese (Komatsu) 2 stroke Briggs used to sell, plus the Suzuki and Kawasaki 2 strokes, and now the Fuji Robin 2 stroke. All of the others seem to have excellent reputations, and from what I hear so does Robin. Parts should be available for all of them, from the Japanese source. I haven't personally seen anything much in Outdoorking archives on Robin engines, but as I recall Bruce regards them as outstanding. Hopefully we'll get a good archival contribution as you become familiar with this engine and get it working properly.
