How to move carb needle
I need to move my needle jet because I'm running rich mid-range right now. I got my main jet dialed in right, just bogging out half throttle. I have never had to move my needle jet before and I have no clue how to even do it. I took the 2 screws off the top of the carb and pulled the slide out, but I cant figure out how to move the needle. Any help would be appreciated, thanks.
