No need to yell. I was responding to the amount of needle adjustment recommendation.
I did read the original post and yes you can tell by sound while in the air. Someone else already said that so I added the other.
When you adjust on the ground for peak rpm back it off slightly, perhaps 1/8 turn or maybe 100-200 rpm.
I was just trying to point out not to make a very large, 1/2 turn is large, needle adjustment at a time.
