Lean, Rich, what is going on

2 things to keep in mind. 75% to 100% throttle is entirely the main jet size. Below 75% is the needle setting. If you change the main jet size, the needle may occasionally need adjusting.

Sounds to me like you may need to change the main jet first. Once you know that is good, adjust the needle accordingly.
Thank you something I should be keeping in mind too.
