I use this set of flexible feeler gauges shown HERE, they work real well with the recessed tappet adjusters.

If your Mikuni-clone carb looks like This One, I have a baseline setting that I go by. I go up to a #95 or #100 main jet, a #17.5, #20, or #22.5 pilot jet, I set the jet needle clip in the 4th slot from the top, and start with a fuel screw setting of 1.5 to 1.75 turns OUT from seated. Keep in mind that it is a FUEL screw, you turn it OUT to richen the mixture. I'm at sea level, the above settings should work for you.
