Randy, For starters, point the hole just out of sight from 90 degrees looking straight down the venture, like 95 degrees.
From there its a matter of finding a sweet spot between 95 and 4 o'clock(what ever that degree is). It is a pretty fine adjustment and may not be that important unless you have special equipment. I'd try 95, then 4 o'clock, which ever works best thats good enough. Any where in that range is good enough for a beginner or intermediate flyer.
St collet tightning is touchy, I set mine so the needle valve is hard to turn but not that hard to make a small adjustment that easy, once the final appoximate setting is found, you may tighten it a bit more, never locking it tight enough that the needle won't turn with your fingers.
Thats my opinion and the best I can discribe it.
