That will depend on which way the carb is installed and the arm is oriented. It's best to have the cowl off so you can see everything when setting up. If it is still not visible, try a little dental mirror or something.

You can also use a thin piece of wire bent so you can get it inside the carb, I use dental wire and it comes in different thickness so I can even set my low end without seeing it. Just fit it in aND FEEL WHAT WAY IS OPEN AND CLOSED.

Rotate the throttle arm and you'll notice it moves in and out .Farthest out ,is wide open. closes in is closed. This way you dont have to look down the carb

Insanemoondoggie has the best suggestion unless you have a small mirror to look in the carb.

This is correct, what doggie is saying. I have several planes that have the engines in too tight to see anything so I just set my trim at center and use the wire and EPA so I know how far opened it is for the first start up when at idle so I can trim it up or down as needed, just a starting point but it does tell me when it is open or closed and how far. Like Chuck mentioned, if you rotated your carb forward and back changes. If you have moved it, watch it like mentioned.
