Anyway, I have tried running today and I seem to be getting it. The only problem now is that it cannot idle. Only for maybe 20-30 seconds and then stalls. But for this I will tweak the needle, my guess is the engine is being flooded. My guess is I am still running extremely rich, as if I turn the model I get this brown liquid leaking from the exhaust.

One more question: is it normal, that when the engine heats up it starts running faster even at the same throttle level, or does it mean I screwed up with the break in? Basically when it's cold I increase throttle trim by 25% and it starts and doesn't go anywhere, however, after a minute or two it runs very fast at this trim level and I have to decrease it. Is this normal?
