All the info, and scroll down for the important idle speed info:

The idle by-pass screw is the correct idle speed adjustment method used to adjust idle speed, not the low speed screw that contacts the primary throttle shaft. This screw controls the amount of air bypassing the throttle disc and therefore controls the idle speed. The idle mixture screw is usually sealed at factory but it can be adjusted to give a better idle quality. However be careful because it may cost you a little economy. These engines are specifically tuned lean, not for best vacuum or idle quality.

Base bench adjustment - Mixture screw out 3 turns. Idle by-pass screw out 2 turns

And, I'd agree with others, you need to find TDC and make a timing tab (and check/set the timing).
