Stihl hl 95 carburetor leaking fuel problem

[High climb]

Can anybody help with a leaking carburetor on a stihl hl 95 .

It's was working fine then just stopped and seems to drain a tank of fuel through the carburetor. 

Any ideas or help would be great or is it a case of a complete new carburetor.

Something must be holding the needle controlling fuel into the diaphragm chamber open. Either the needle tip is worn or some crap has built up and pushing the diaphragm

Thanks I will have a look..

Yup, sounds like a leaking carb needle valve to me - it causes fuel to piss out of the carb and either in to the engine or in to the air filter, this is the most likely cause.

Weak spring, stuck needle or incorrect arm height are the common ones, incorrect diaphragm is possible!
