Does it have adjustable carburetor? With it running, the high speed screw would need to be adjusted to get it to run correctly. If the carburetor is non adjustable, I would look for a new carburetor with adjustment screws,

They are to cheap to try any kind of repair. See the above link. If yours has the odd screws, you can use a piece of tubing slipped over the heads of the screws to turn them for adjustment.
