Default mikuni bn carb question

on my js 550 ski I was told on pwc that this carb is not stock(wonderful just my luck) anyways there are three settings finally got to sit on here and research to help understand more of what is going on with them to try and tune it so I can run it better.

Can anyone tell me witch needle is the the low-middle-top range adjustment screw? one is on the throttle side and other to are on the other side.

It runs and idles great but mid blows and top end isn't there seems to be flooding it so as long as I know witch ones witch I can better tune it.

All help is greatly appreciated guys
