Hey Everyone. Thanks to all who replied. I finally got the MT2 running good. Basically Im running it 3 turns out on the LSN and 3.25 turns out on the HSN. Works like a champ. For those who need the number of turns to make it flush on the LSN, just as I preferred, its 2.5 to 3 turns out on the LSN. The Idle Screw should be set around 1.5mm out of closed on the carburetor opening. It was recommended that I try the OS .18 CV-RX Engine, so I bought one for my other CEN MT2. I will spend the weekend braking it in properly. Even from opening it from the box, I love this engine. A much larger blue heatsink to help keep the engine cool. Much better than the factory NT .16 engine. Does anyone know of a larger aftermarket finned heatsing for the factory installed CEN MT2 engine? Thanks again to all..
