Sounds like your fuel adjustment screw.
It has a o ring on it.
Carefully undo the the lock nut, then count how many turns till out.
Replace o ring, replace screw the same number of turns.

Better off, mark accurately with a scribe with reference to the top housing.
Then do as mentioned.

o-rings and seals on the wayout.
Replacing the o-ring/s will put extra pressure on the seals so it'll leak again latter on down the track but that time around it could be the seal going rather than o-ring/s.
