WANTED Walbro 500-24 Adjustment Tool for metering lever

[Lee Sluga]

on the above pic there is a protective carb covering the other end of the screwdriver not allowing a view of it

Did you mean protective cap? If so, what is normally under said cap?
I can't say I've ever seen this exact tool in person, but what's the main purpose of wanting or needing it?
Is it basically one of those reaaaally fine screwdrivers that they made small enough for fitting through the hole in the limit caps,
but still being capable of turning the screws underneath them?
