Okay dude ... I will make a guess that the needle valve is not seating properly, or the float is set way too high. If you had a dealer do it take it back to them and demand they fix it.
If the needle seat is seated in the carb housing, not sticking, has the o-ring on the seat and the needle and seat are in good shape (no grooves in it and clean) then the float is likely adjusted too high, or may have a leak in it causing it to sink into the gas in the float bowl. To lower the float level, assuming it hasn't any leaks in it, you have to bend the tang that rests against the needle valve. Make sure you bend the tang on the float the right direction for where it pivots and where the needle valve is. As the gas is used out of the bowl the float "falls" and allows more gas in. When the gas level comes up the valve is closed and stops gas from entering the float bowl. There is a measurement for the float level and you should find out what it is for your carb. Then you remove the carb and hold it in such a way that the float is just touching the needle valve when the pin is perpendicular with the ground. (about a 30 degree angle)Then with a tiny ruler, that is accurate, hold it straight on the surface that the float bowl bolts to and measure to the bottom of the float. Thats how I do it anyway and it always seems to work.
If it runs it is likely spewing a bunch of black smoke and backfiring? Once you get it all running good you may want to clean out your airbox as it may have spit a bunch of gas in there. You should also may want to clean and regap your plug, or replace it ... still regap it ... never trust the gap from factory.
Something else it could do if it has dumped a massive amount of gas into the cylinder is wash the cylinder walls down, reducing compression, and it could lock the cylinder if the combustion chamber was filled with gas. I would definately pull that plug and turn it over a few times. If it is full of gas squirt a little bit of engine oil into the cylinder and crank it over a few more times before reinstalling your plug.
Good luck with it and I hope this helps some.
