Default Air mixture screw thingy... I think

Ok, so after many weeks of not being able to ride, I finally have it up and running!!! I have 2 questions.

#1. I was playing with the air mixture screw when my bike was idling. I noticed that if I turn it clockwise the engine starts to rev higher. If I turn it counter-clockwise, it revs lower. My question is what is the best adjustment for the screw and if I have it too tight, will it reck my engine?

#2. My engine starts to make a bbbbbbbbbbbbbbb (not smooth) noise at certain throttle positions. When I twist it some more, it sounds like, mmmmmmmmmm (smooth). What could be going on with the engine? I asked my dad and he said that it is because the engine is out of balance... is this true. If so, how do I fix it?
