Without being too cryptic......in on the bottom, out the top, and the middle goes to the crankcase (pulse line). Now that only works if the bore is horizontal....some were vertical. 2 strokes also run upside down and sideways. Not all model carbs had return lines or external pulse lines. Gee, did that help?
