Ok, point taken on the jitters while tunning the engine on the Eagle 2 - 2 stroke. I am currently having a nightmare of a time with an Enya40 that I FINALLY got running this year. (haven't flow but once this year, and just learn how to last year).
I don't have a remote needle valve, and some are swearing my engine is great great great and that a remote valve would ruin it. It's perfect and should be great great great. But the fact that I am not in the air and the engine is SO very finiky makes me think that I shouldn't listen very much to many and start listening to a minority few that think the cheap OS engine would be a dream fix for me and my rc'n woes.
Good luck with that plane. I built my from die-crushed kit. At the very least I figure I will know what needs replaced when I auger into the ground.

Oh no! wait...
