: WD40 normally fixes everything except personal problems, this is one more!
the temperature expansion of aluminium is about 25% larger than the temperature expansion of brass, so heating the carb body to about 100°C (remove all gaskets before doing this) might help to loosen the stuck brass tip.
If not, look at the bottom of http://www.bingpower.de/german/service/ersatzteile_konditionen.html and try to contact the guy named there, maybe he's got some more ideas.
