Blue, the carbs arent like what your thinking. There are no adjustments for air or idle screws or any of that good stuff. If they are like my 2000 Johnson 150 all the jets are fixed no adjustment required. You take each carb off, unscrew the bowl, shoot some carb cleaner through the jets, blow some compressed air through them, replace the gaskets, new needle, seat, and float, re-install. Sounds complicated, but its not.
The only thing that can be tricky is the Lync and Sync but alot of motors you don't have to disturb the linkages to remove the carbs. Trust me I have rebuilt carbs on 4 different motors and I'm no master mechanic, its that easy.
