Welcome Zilla! You is in the right place, no question too noob. You might have seen some of this stuff hunting around on the board, but here's some tips:
Have you balanced your top? Re:

It's a little easier to balance a top with a fixed tip, but you can use the same process.
Also, be sure to tape your BK up! Get some electrical tape, and tape the cap to the body. I like to do two wraps and match the end seam to the start seam, stretching it only enough for the tape to contour to the curve of the top. BK's will break easily if you don't tape it up.
Does the bearing spin freely when you flick it with your finger? If not, your bearing might have gotten jammed up a little if you hit it really hard tip down, or ya might already have some dirt in the bearing. Easiest way to clean the bearing is leave the top assembled, and put it tip down in a cup of mineral spirits (enough to cover the bottom inch of the top) and let it sit for a while. If it's jammed... we'll talk some more
