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
