There's a number of things that can cause that.
I've found it to be pretty common with replacement and rebuilt carbs when the arm on the throttle shaft is of a different length than the original. There should also be two springs on your governor control rod, one in front and one behind the block that connects the rod to the governor. Internally, worn, tired or broken springs can cause it. A bad thrust bearing can have the same effect.
Where you're hunting, one of the easiest things I'd check out first is the governor-to-carb link on the left side. With the motor stopped, find the rod that connects the carb to the governor and remove the pin and clevis at the front end where they attach to the governor arm. Then set your throttle lever (at the seat) fully forward. Go back to the carb and hold that rod and the governor arm both as far to the rear as they will go, without putting tension on the spring resistance you'll feel in the governor arm. Then thread that clevis (if everything is there, there'll be a jam nut up against it) whichever way it has to go so that you can get the pin back through the clevis and governor arm.
That may take care of the hunting-- if not there is another adjustment that may fix it, or you may have an internal problem in the governor.
And even if it takes care of the hunting, it may still not give you back full range on the throttle control.
There's a couple of the guys who have had some success with that by straightening and bending the control rod from the lever to the governor to change its length. I haven't had to do it, but maybe one of them will chime in with ideas in that direction.

Today's Featured Article - Talk of the Town: Winterizing Engines - To Drain or Not to Drain? - by Russ Berry. What is this strange attraction I have to equipment and machinery? How did I get this way? I came from the suburbs and own a small horse farm in rural Loudoun County, Virginia. You can call me a "weekend farmer." The local farmers do. Does it bother me? No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
