Aero nut

I have a converted Ryobi 31cc engine that runs great as a gas engine with magneto that I would like top try this on. I know Pete at wackerengines has the glow adapter for it. What glow fuel and gas ratio do I mix to give this a try? I also have a 11mm carb I plan on using on the Ryobi. I would like to use this engine on a Tiger Moth that Nitroplanes has on theit web site.
