If you post some pictures as you go, we can have a thread on sorting out that hunting problem, BB. It isn't uncommon for the governor arm to be bent, so it is worth checking for clearances and free movement before you resort to stronger measures. Then, the first step is to clear the fuel system, which is easy to do.
You begin by removing the float bowl, putting a cup or something underneath the carburetor, and observing how fast the fuel runs out when you turn it on. If it runs freely, that will demonstrate that the tank, tap, hose, and needle-and-seat are all clear. Next step after that will be to remove and clean the main jet, which is also pretty easy. After that, though, you have to remove the emulsifier (directly above the jet) and blow carb cleaner through the various holes and passages in it, and the carburetor body.
