This is supposed to be a manufacturers support forum but you seem desperate for info so I'll tell you how I do it. (assuming that the engine is run in and tuned correctly).

I make sure the engine is primed then flick the propellor backwards about 1/2 a turn towards the compression - the glow plug will kick it into the right direction and it will run. On most of my properly tuned engines, I can just do this by flicking the spinner.

Otherwise They will also start in the same way that you start your 2 strokes with a chicken stick. - just make sure that you run the stick past the compression stroke or they may kick backwards (Same as a 2 stroke).
