KLE Carburetors help!!!!!

[Kumuya]

Hi guys,

Together with a friend I make my KLE pieces , I've changed all 3 chains inside the engine, new piston rings, chain tensioner, some bearings, all gaskets .... is now like brand new, entire frame repainted, assembled all together but now i'm in a big problem

I've changed the vulves from carburetor vacuum and other sealing gaskets from carburetor .

My big problem is that when I fill the carburetor with gas it starts to leak from those 2 holes on the air filter side, that means that I will have a full air filter with gas and also that the gas will be in oil recuperator in air box so it will drain mixing with oil inside the engine.

I've changed all parts, on floating compartment, measured the level but is acting like it cant close the fuel suply line, but on checking it look like closing suply line it works.

I'm out of ideas, everyone I called ... never heard about this problem ..... if you have any ideas it will be fine .... after months of work I look at my bike and going "wtf mate!?!?" .

Thank you for any ideas that can help me solve the problem.
