This image is when you're looking over the TOP RIGHT side of your carb and looking inwards. Notice it's the screw with a spring underneith. I just had to help my buddy out the other day and did this on his '94 Dyna.
Oh, and don't go wild turning the idle TOO low - you don't want to reduce proper oil circulation pressure. I think they recommend 900RPMs for the Twin Cam?

There are two carb adjustments you need to make. (1) Idle Fuel Mixture and (2) Idle. Twin cam engines must idle between 900-1,100 RPM otherwise your top end will be starved for oil. Don't try and get the potato-potato sound!!!
Invest in a Harley Service Manual. It will be the best money you'll spend.
