My motorcycle drown

I have a 125 scooter, which was going very well. I took her to the workshop to do the review, change of oil, etc., and they tell me that the air filter has also changed.
I take it after the review, but the next day after doing 5 km, the motorcycle starts drowning, giving stops, and finally stops at all, without it being able to tear it out. Can it be the carburetor? Does the change of the air filter with this?
Thank you!!

Hello, I wanted to ask you if the motorcycle does the fault when it heats the engine, and if then you let it cool ??, in that case it would be a vovina problem. And it is easier to take the filter and try if it does it, taking into account that if you take out the filter the motorcycle would not go well for having a lot of air, but I would not have to make the failure that makes you. Good luck I hope you can solve your problem, a hug

Thank you !!, I already look at it, but I did not start cold, I don't know if it could be an impurity or water in the carburetor ...
