I have a Nexus 30 with an OS 32 in it and I am having a problem with the engine leaning out in hover. At idle and during take off I have a good amount of smoke coming out but once I have been hovering for about 30 seconds or so the smoke trail starts to dissappear and then the engine begins to bog out. It does not die though and once I bring it back down to idle on the ground it starts to generate a little smoke again. Currently the low end is turned out about 2 turns and the high end about 2 turns also. Which side needs adjustment on a problem like this. I have tried adjusting both but have had no luck. This is my first heli and I am only hovering right now and used to tuning airplanes so I have no idea where to go from here.

I read something about drilling a hole in the carbuerator. Is this an option and what exactly does that do for the engine.

Any help would be greatly appreciated.
