My tt250 has never run this well. Maybe my answer is to just leave the stock carb on lol.

Stock carb.
35 idle jet
Main jet 112
Needle position 4
Fuel screw 2 3/4 turns out.

Here's a video.

4 seconds into your video shows the stock carb vent(?) capped off. Is that correct? If so, why? This is a very slow learning process for me. Thanks to everyone for all the great comments.
