OK I have my carbs apart and it is asking me to remove the air screw which I have identified. But it has no slot, just a whole in the middle???? How do I get it out?

That is actually a cap. The air screws, according to the manuals, were "factory set". Under those caps is a slotted air screw. You will need to drill out the caps, being extremely careful to not drill the head off the air srew. The screw is recessed under the cap around 1/4" to 3/8".
Good Luck on your project!:-D

Great. Thats a bad plan. I think I will skip that part... Also in carb one (so far) I am missing the pilot jet plug. Is this important?

Your screws are EPA set, and plugged from the factory. Let me offer you a SOLID piece of advice.... If your engine idles good, and has good acceleration from a dead stop, simply leave those plugs and screws intact. The air screws are loctited in place and directly on top of the screws is a steel plug. Many of us have been forced to remove the screws for a complete carb overhaul. I personally destroyed 2 good carbs in the process of trying to remove the plugs. It is a VERY difficult process.

Are these CV Carbs? Should be on an 83. Your question is confusing me. Are we talking about the mixture screw (on the top of the carb, engine side, usually has a plug over it) or the air jet (inside the venturi, airbox side)? I just happen to be working on my carbs, so lucky you, we get pictures to talk with 
Air Jet...
Mixture screw...
The mixture screw usually has a plug over it. The plug is aluminum, and will have a very small hole in the top of it. I used a decking screw to thread into the small hole and once the plug broke free (started to rotate) I just pulled the darn thing out. Easy cheesy. Contrary to the earlier post, I would recommend removing the mixture screw, if only to replace the o-ring that is at the bottom. If you set it up about 1.75 turns from seated your bike should run well enough to begin the tuning process.
The air jet will have a number stamped into it, and that should be referenced in your service manual. Something like 150, 155, 160, etc. It will be brass, and has a screwdriver slot in it.
