float bowls setup wrong overflowing the bowls. should be coming from the vent on bowls but could also go back into the air box or into the engine.
Check your oil for gas.

Need to remove float bowls and adjust the float levels - bend the tang.

Hi, Can you tell me exactly how it work? why is is purring gas?

Definably floats sticking overflowing with gas. A cool tip that really helped me with sealing the needle and seat and preventing sticking floats is to polish the brass seat. I use mother's mag polish on a Q-tip chucked up in a drill. Follow up with a couple clean ones to remove all residue, flush with carb clean and you should be set. Also check float height if yours have the adjustable metal tang. One last thing to check is if your float has a hole in it. Stick em under water and look for bubbles. Normally when it overflows gas comes out of the hose that comes out the bottom of the bowl. I would check those for blockage.

Thanks for the information, the gas is coming out from the clear tube not the black tubes. The floats are in good condition. I have already changed them and cleaned them. Once again, the gas is leaking from the clear tube. Please advise

That looks like the drain tube that is attached to the air box. The only way I could see gas coming from there is if a carb overflows and gas flows out from the air intake side of the carb. Maybe there's some fuel leftover from before your carb repairs?
