It's been a while since I tuned this carb, but here's what I remember I did to get it to run as good as it does, and it will haul; no flat spots, no surging, no popping or missing.
1st. I tied open the choke. It does nothing now. The bike starts right up without it. Even after setting for a few weeks and cold.
2nd. set the Air By-pass and Idle Mixture screws to initial setting. If I remember correctly they are both just about where I started and make almost no difference at idle.
3rd. I set the idle using the fast idle screw. I know folks say that is a no-no, but it worked for me.
The bike idles about 1500 RPMs. Here's a link to a video, but the wind is loader than the engine. Ol' Wing Road Test (I'm a lot better bike mechanic than cameraman.)
Hope this helps. Bud...
