Sorry to be a "I told you so" but I think I mentioned the float needle about 8 posts ago. If it is this the float should have a tang on it that can be bent up or down...where the needle actually fits. If the whole thing is plastic...and quite a few are... then you are correct it is not adjustable.
In this case you will have to fit a new needle and or float. If this does not cure the problem then the float needle valve will have to be replaced. Most are unable to be removed but a trick I used years ago was gently tap the valve out a little to increase the pressure on it from the needle.
Now this was on a vintage carb with no possibility of replacement. This carb was also a lot more robustly built than many newer ones so could take this kind of treatment. Be well advised that to try this on a newer one made from thinner material could damage the whole thing beyond repair.
Good luck
