Way OT...Any RC aircraft people on the list?

You can mount them upside down, sideways, or backwards.  It won't make a 
difference.

The model engine carbs use the vacuum of the engine to draw in fuel, not 
gravity.  There is also a slight pressure from the exhaust that runs to the 
tank, this helps some, but is not strictly necessary. (they will run without 
the pressure line, just not as well)

Someone at your local flying field will be able to demonstrate the "point 
plane straight up" method for testing mixture.  When the mixture is set 
correctly, the engine performance won't change with orientation to the 
ground.

Airplane guys are normally happy to help a beginner.
