you will have to do the fine adj, by eye, after you fire it up.

It's called "tracking", where both blades rotate on the same pitch/plane/track.

run it up at 0 pitch and eye ball parrell to the blades, it helps if you have one marked in some way so you can tell them apart.

both blades should track the same, usually you will raise the lower blade to make them track the same.

Yes, pop the ball link off the lower blade and adj., usually shorter is more pitch.
