Thanks for all the info guys, esp for the long post by you, Chuck.

Seriously, I didn't even know that you can scew those high speed needle holes . I thought you have to get a hex wrench of just the right fit... mark of a newb[:-]

Either way, I successfully maidened my Mayhem 3D, such a sweet plane, and I ran the engine on the rich side because I was there on the field by myself, and could not possibly (without a tai trap) do all the fine tuning myself. The engine never skipped a beat, nor did it ever hesitate or flame out.

I am officially a slimer now[8D]
