Thanks, Ken.

I'll wait until I get some help at the field. For now the only thing I can do is move the throttle linkage on the servo end in towards the center. It's already out all the way at the carb end.
I seem to be getting very smooth linear motion now ie. when the stick is at low end the carb opening is barely open, at half stick, it's half open, and at full stick it's wide open, which is the strange thing. Maybe I'm running too lean? I have the engine running a little on the rich side according to what I was told at the field - about three and a half rotations out from all the way in on the needle. The engine is running great, alot of power and smooth at low end and high rpms as well. It just seems to have alot of pull and high rpms at only a few clicks of throttle on the stick. I don't know, maybe it's just me since I don't know what it's supposed to be like. I do know that on the club's trainer which is also a LT-40 with a 40 size engine (mine is a 46), it doesn't work that way so it doesn't seem right.

Oh well, like I said I'll ask for a few opinions at the field from the guys I trust the most.
