I'm not familiar with the 250x but....

Main jet may have fallen out..... it does happen;)

Check the choke lever too.

you might wanna cheack if the main jet has fallen out. what happened to me was one day it was running fine, but the next i would only run on chock but would still not idle. when i decided to look at the inside of the card there was a 1/4 in. layer of green gunk in my carb i cleaned and now runs perfect.
