Use fuel with 20% oil, mostly synthetic, 75-25 or so, Run it with a 11 x 4 prop, run the fastest 4 cycle it will run in, then turn the needle just into a 2 cycle for 10 seconds at a time. rotate back and forth between the 2 setting, I would run 4 ounces at a time, and try to use 1/2 gallon of fuel. When you decide to run it in a plane, use a 12 to 12 1/4 x 4 to 4.25 prop 2 blade or 11.5 to 12 inch 3 blade with about 4.5 pitch. We burned about 5.5 to 6 ounces of fuel piped, and a little less run on a muffler, Use a hot glow plug, like a Glow Devil 300, big bore hot, etc
