Methanol and Klotz works well, we use 6% oil in out racers, but a sport engine doesn't need that much...I would think about 3 or 4% would be fine..Nitro is not needed.....We have run the SAME glow plugs for the last 2 seasons, they're still good....McCoy #9 plugs, 289cc engine, 9000 rpm......
Engine looks like a Quadra 80 with the crank reversed..Probably easier to make a mount that way.....
