Try cleaning out the idle jet on the side of the carb.
Unscrew it and pull it apart, then blast it all out with carb cleaner. Its sorted mine out many times now.

Yeah, I just refurbed my carb too. I can't of cleaned it all out that well  :mrgreen:
And anything thats been pushed or sucked into the carb will cause you these problems. Its worth a shot. Mine took about 3 cleans and starts with the idle jet to get it sorted. I blasted in the carb where the screw sits too.
