seized brass carb jet

[EazyDuz]

I don't know why this seems to happen on so many bikes.
Pilot jet seized in carb body. Flat head all chewed up. Tried plus gas on it and lightly tapping on it with a hammer to loosen the threds.
What next? Preferably something I can do without removing the carb from the bike

You'll have to replace it but...can you get a pair of mole grips on it?

They have larger than usual slots in too so tend to get mashed up when people use screwdrivers that are too small.

Something very pleasant about the nice "crack" you get loosening a tight one too

I heard heating the screw with a soldering iron can help. Someone even suggested nitric acid to melt the brass, sounds a bit daft if you as me..

getting the whole carb piping hot might help. Aluminium expands much more than brass.
