Carb trouble!

Got done with a top end today on my 98 KTM 250, and I had pulled the carb and checked the reeds. I did also split the carb and checked the floats and what not and everything looked and seemed to work just like it should. When I put it back all back together and got ready for the break in, I turned the fuel on and it trained straight out of the drain tubes coming from the carb. Float stuck? Took the carb back out and it didn't seem stuck at all. No clue why it's not doing it's job. As soon as the bowl fills up, the fuel flow seems to keep on going and right out the drain tubes.
Any ideas? Please help

I didn't replace any parts, but I guess the float needle isn't sealing for whatever reason. I was carefull but somethings gotta be missing.
