Hi Again, I did the changes you recommend me. First, I started the engine with the factory settings about the HSN, which are 1.5 turn, and I turned the LSN 3 to 4 turns. The engine started well and fast, and I let it to idle for a while. However, I realized the temperature was rising very fast. It went to around 250, and I shut down the engine. After that, I didn't touch the LSN, but I turn the HSN to 3 turns, and I started the engine. I accelerate a bit the engine, and it seemed to respond well, however, again it went to 250 really fast, in around a minute too. After, I turn first the HSN to 4 turns, and after again to 5-6 turns, but again the engine's temperature rised very fast. It seems that the engine doesnt respond to the HSN. Even when I open it around 5 to 6 turns, I didnt see oil coming out of the exhaust, only smoke, white smoke. Could someone tell me if my engine is defective? If so, which engine would you recommend me? I would like to have a decent one. Thinking in a Top .12 or Rex .12, or Picco engine. I have a Mugen MTX 4.

Thanks again for all your help.
