Stupid Question, need quick answer: Idle Screw & Air/Fuel Screw

Having trouble lining up the diagram I have with the carb.

Can someone tell me or post a picture of which screw is idle and which screw is Air/Fuel?

Also, which way do I turn for richer?

Thanks!

idle has the spring on it and sticks out some, air fuel is the small screw by it that sits more flush with the carb. backing out the air fuel screw makes it richer

Idle points towards the ground?

yeah they both do but the idle is bigger, has a spring on it, and has some (teeth) on it so you can turn it with your hands
