how many turns out should i start with on the idle mixture screws. and what is considered a complete turn??????? i started with 4 turns out and thats 4 complete turns i think. liek go around once and then go around again to make a complete turn pls someone help

 

One complete turn is ..... one complete turn. 360° rotation.

If this is your factory computerized Q-Jet, the threads are a very fine pitch, and the screws do almost nothing anyway. Set them to 7 turns out from full in, and leave them alone; and make your idle mixture adjustments with the IAB valve.

 

I've noticed that, too. The threads are about twice as fine as earlier carbs, so it takes a lot of turns to make much movement. You can back them out so far they almost fall out of the carb and you still won't be excessively rich.
