Default Couple of Carburetor Questions

Hi all, I finished my 49cc install, having a ball with my bike but need advice

Im at 5700 feet altitude and think Im gonna have to do some jet work so I have a couple questions;

---when I replace the main jet (I'm going smaller) do I have to replace the needle too?

---how much of a gap should the slide in the carburetor have at closed throttle (idle)?

Thanks all for the help
