you answered your own question bro..they are plugged up...you need to take them off and spray lots of carb cleaner in them and then blow them out with air....mine did the same thing...put the air right to the small brass ports...also sounds like you need to get them synced as wellas setting the floats and all from scratch bro...make sure all the float needles are good and the seat area is not damaged....but if it is coming out of them when it is running you have plugged carbs for sure,and possibly other issues too...
