Unhappy Engine troubles

I got my car finally... It is an OS CZ-R .12 engine. I am running Blue Thunder 20% fuel through it. Okay, When i start it and let it warm up , it doesnt idle like I want it to. It idles too high. When I try idling it down, it just ends up richening it and flooding it out. I have no idea what to do.


I know the engine looks like an airplane engine... but its not...

It could be to rich, If you turn the idle down it should be getting less fuel (less air to pull the fuel into the engine. Set your high speed first, then the low speed. The idle should be the last thing you set on the engine.
