Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I assume the "air screw" is the mixture screw? There's so many names for that thing...
Typically, the setting is all the way in, then out two to three turns. Be very careful with the first part, gently seat it. After that, fine-tune the adjustment using the highest RPM method below.

You are correct.
The OFFICIAL name for it is simply "Pilot Screw", but I have always called it the "Idle Mixture Adjustment Screw", just to fully identify what it does.
Personally, when I rebuild a set of carbs, I will turn them out three full turns. That gives a slightly-rich mixture (a bit of "choke", if you will) for easier starting. You will still need some "choke" to start the engine. When it is warm enough to run off-"choke", you should warm it up a bit more, then start the fine-tuning process.
