Carb petrol leakage

[axolotl98]

Just had my Yam 115 mod. 91 set of carbs professionally cleaned, and changed floats, gaskets, pilot air screws, main jet o-ring etc.
Installed the carbs back myself, and the cyl 2 carb, seems to be leaking petrol from the lower part of its front end.
It is like dripping petrol, and the engine does not sound healthy at tick-over while it also does not seem to rev freely...
Any ideas what might be causing this ?

Just a thought. start with the obvious. I just did carbs myself and put the gasket on without taking the old on off. I caught it but was very close to not. Cant hurt to make sure all the old gaskets are off
