David, I have been running the SE for about 4 years now in my pylon airplanes. I'm going to assume the timing is the same ( the piston and liner should be interchangeable ) With that in mind, the engine runs well on 15% nitro and 18% oil. Use a medium cool plug. I have been running an Ultra thrust muffler and mine likes being right at 16K. The Rossi 10mm carb fits and works well on the .45. As far as props go you will have to experiment. I run a 9X7.5 on mine so you may want to start with a 10X6, 11X5 if its a draggy airplane.
OK you just posted pics. You have the 3X2 version ( I had not heard of this ). It will have lots more power and will like a fair amount of load. Run a longer header then normal. You also have the standard 8mm carb. All other info still applies
