Dance steps, need some help!
77cruiser:
Good. When you thread from the top it's easy to get too deep.
novadude:
I would be very careful with any kind of press-in solution on those lower idle air bleeds. If a press-in bushing comes out, there could be bad consequences. Make sure you have a good tight press fit with the rivets, as anything that is not very secure in the venturi / throttle bore makes me nervous.

Yeah, I thought of that, I used a punch tip inside the down channel from the bottom because it goes right behind the bleed hole and then drove the rivets in against it to ensure that they are swedged into place. The last thing I need is for one of these to go bouncing around inside a cylinder.
But like I told 77cruiser, I'd rather use the set screws as they can be changed easily if need be. This was just a trial alternative in case I had no other option.
novadude:
Using the punch in the down channel to back up and swage the rivet is a great idea.
Cadman-iac:
Thanks Novadude.
Another question, if you're changing a set screw in the air horn to calibrate and the carb is still on your engine, how can you keep the set screw from falling into the carb? Do you guys use a bit of grease on the end of the allen wrench, or some other method? What do you recommend?
I have to use an over the fender creeper in order to reach the carburetor on my truck, one, because it sits high, and two, because my poor old titanium reinforced spine can't handle climbing into the engine bay anymore.
