Wow, thanks for sharing that
uawelder, just spent 30 minutes reading it and getting my head around it. Very interesting.
Whoever

I can see that by fitting a larger diameter/leaner needle with the same clip position, and all other components remaining the same...the only effect it has is to lean off the first 1/16 of throttle opening! Displayed by the red dotted line.
To be honest, I was expecting a larger/leaner needle to lean off the mixture over most of the throttle positions, obviously I was mistaken.
