Sounds like you either got some dirt in it from that first cleaning or knocked the float out of adjustment. Hate to say it, but you need to take it off again, clean it out really, really good (make sure you're not forcing some dirt into a different place), then blow everything out with compressed air. It's best to remove the slide, jets, airscrew, etc. to ensure all the dirt is out of those areas. Once that's done, reset the float level to factory specs and button it back up, reinstall, and readjust air screw and idle speed.
It goes without saying that your airfilter should be clean and re-oiled (not too much!) for best results.
