Where to start ! These engines run well out of the box. You do not need too much nitro, maybe 5% to start. The +- on the carb adjusts the mid range fuel setting for the engine. Start with it in middle position, this is when the slot on the brass screw is hoizontal. I am sure the barrel turns 360 degrees on your carburettor. It is very important to make sure that the fuel delivery increases when the barrel is opened. this may seem obvious but it is easy to get the barrel position 180 degees out. This can be proved by blowing into a tube attached to the fuel intake and opening the throttle, you should feel the air increase as the throttle opens.
