The main jet is only used at Wide Open Throttle. What you will mostly be using in the mountains is between 1/4 and 3/4 open, where the mixture is set by the needle. You can note when the mixture is too rich that the engine doesn't easily pick up on accelerating and sounds like an Opel GSI instead of a Toyota Corolla GT Twin Cam.
What is KKH?
I wouldn't take the top off the box because 1) it doesn't help
2) you collect dirt and/or water
Have you already mounted a K&N air filter?
Have you already modified the exhaust?
