yea, its that stinkin' tube. My needle looked OK but the slide and tube showed a bit of wear. Does not take much to affect smooth running.
Could also be a bit of water in float bowl. Drain it for luck. Maybe a dose of Sea Foam or Techron? Also, re-check fuel/air screw setting (mine vibrated OUT) and reset idle speed.

Good luck!
