Joe Just (Big Country Joe) handles the Leo engines, or at least *did*.
This thing has been a one flip start ever since I put it on the plane. Super friendly, very good usuable power. Not sure what Scott Riese did other than install a venturi and NVA and fit it. Joe or Scott can give that info. I got the last two in a special from Joe that he had at the time. I believe that they were only marketed as R/C. It seems VERY similar, running wise, to the Magnum square head 36 XLII. I have not tried to run it in a wet 2, but I will. It's just running real good the way I have it set up right now, so I haven't changed it around. Is it an Aero Tiger 36? No way, but it is a very good little stunt engine and if you cannot justify buying a AT 36 right now, I would recommend it for a .35-.40 traditional size plane.
