Fine Tuning 1999 Johnson 60

I'm hoping someone can explain a few things about this: I've replace
the plugs, rebuilt all 3 carbs, cleaned fuel pump and changed lower
unit oil...
Now, today I fine tuned the low speed jets to where it stopped
bucking and smoothed out. I don't know what the intermediate oriface
( small brass screw at top of carb ) is for or where to set it! Also,
what should I watch for to avoid a lean condition? I've adjusted the
metal linkage off the 3 carbs so that the rod touches the black
plastic throttle plate, not sure if I needed to do that or not though,
does this give it too much air?
Any advise about fine tuning will be a huge help since this is my
first outboard... Tach will go to 5.5 now and runs fast and smooth on
the water, I just want to be sure it's adjusted and running safely
( no lean conditions )- Thanks!

I meant to ask, does anyone know a good source for OMC keys? I need a
spare #75. I found 1 site, but they're $21 a piece and you have to buy
2!!! A bit much for a key! I've checked the hardware store, they can;t
make them, so what do you do when you need new keys??
