Leak on top of carb...

[TomInCologne]

Hi guys,
this is puzzling... at least to me...


I came to the car yesterday and found a puddle of fuel under it, about 1,5l. My carb has always been leaking but it was only dripping, not a lot. Now this is new, 1,5l is definitely too much...


Looking at the carb, the fuel seems to come out the top through the accelerator axis or thereabouts. Does that make sense? I thought that if the valve in the float chamber is leaking, it would like out somewhere on the bottom of the carb...

Thanks in advance,
Tom
