I may not make any friends with this post but.... Mike's ad for those screws says "Straight from the Harley world".. if in fact those are HD thumbscrews there is a good chance the taper is different from ours. HD's have a single, larger carb feeding 2 cylinders, thus the difference in taper. I had HD screws in my carbs for awhile til I realized that they provided little to no adjustment. There was a thread or two about this many moons ago complete with pix and it ended with Brent at newspeedmaster.com making thumbscrews with the correct taper for our carbs.
Now, I know Mike (Racedweeb) at BellaCorse knows his stuff, and the "Straight from the Harley world" might just be wording in the ad, but I would check the taper of the needle end of the thumbscrews compared to the d-screws you remove from the carbs just to be sure. I'm just putting this out there as an FYI.. I'm not looking to step on anyone's toes. But I been there, and done dat.
Here's a pic.
