Burn your fingers

You will burn your fingers anyhow, as the starter has been 'engineered' in later meaning there is realy no space to turn the screw easily. In my experience, a screwdriver bit with a narrow tip (blade, not Phillips) does it.

Reading your other post, this is however not the solution to your problem. Opening up the airbox does indeed decrease air resistance but this resistance only counts at higher revs / loads when there is a large amount of air flowing. So, changing the mix at idle will not help you.

It seems, for your specific bike there is nohing to be gained by opening up the airbox except noise. Would suggest, bring back to normal ....

Idle mixture adjust

If you have a carb like the ones in the states it came with a brass plug in the idle screw adjust hole. To get it out drill a small hole in the plug(go slow and do not drill too far you can jam the idle screw in the carb and ruin your carb) then use a sheet metal screw as a puller: screw the screw in the hole you drilled and pull with a pair of pliers. So as you now realize you have to either turn the carb or pull it off the machine to do this. Once you have done this and the carb is back on the bike start at about 3 turns out from lightly seated and with a warmed up engine adjust for best idle. If you don't have the special carb tool to do this try making a screwdriver out of a short roofing nail. Here a roofing nail has a big head and a short shaft, grind a flat blade screwdriver tip on the shaft and adjust away. And yes idle mixure will affect runability. If you cut open your air box you just started a tuning journey...you essentialy leaned out the carb a size or two on the main jet and affected how it handles changes in throttle setting.
