Welcome to JUST ANSWER small engines, let me try to help you !! Can you control the speed if you go direct to the carburetor linkage? You want to check the throttle shaft and the throttle butterfly in the carburetor to be sure the butterfly is not loose or the shaft is broken. Then if you can control the speed, manually, feel the governor lover, does it have push/pull when you run engine throttle up and down? If no feel from the governor side, you have a broken governor part inside the engine. If it has feel, push/pull, the problem has to be external with linkage or throttle cable.
