So I can just leave the 'smoke fitting' on the muffler open? ok.

I am still confused on the fuel hookups.

Looking at these pictures from someone elses setup:

I would think the line 'closest' to us in the picture is the fuel line. Now, in this picture there is a fitting both 'above' (on the 'bottom' of the carb, but the engine is inverted, so its now on top) the carb and below. I can see he has a second line plugged in somewhere where does that go the top or bottom?

From tom's description I would have thought just a fuel line, and then connect the crankcase tube to one of the inlets (still don't know which one since they are 'above and below' the carb. I am assuming it must be the one on the bottom (when engine is upright) since that is closest to the tube.) But in the above pictures I see 2 yellow fuel lines, I don't get where the second one is going if the third inlet is to just be left 'open'

Thanks!
