1. Governor throttle shaft (shaft inside tube between carb. and top of governor housing) may not be engaged properly with throttle shaft in carburetor.
2. See if the brass (or plastic) piece on the end of the carburetor throttle shaft isn't spinning on the shaft.
3. Throttle shaft lever (arm at end of governor throttle shaft) may have broken the pin through it that holds it in place on the governor throttle shaft. This can cause tractor to idle fine and run wide open when moving the throttle lever to a point that causes some movement of that arm.
If you're gonna keep yankin' that throttle lever back and forth, pull it downward so it doesn't drag on the notches. You'll have it wore out before you know it.
