I would have to think that the original chain may have been dragging a bit and the carburetor was adjusted to compensate for it. Now that the chain moves freely the carburetor may need to be adjusted back.
With that being said, I would take it to a local Husqvarna dealer to have them take a look at this issue. This involves safety and nobody wants to see you get hurt over this one. You can find a local service center via the link below.
