I just put a new carburetor on the Tecumseh engine that powers the tiller..it ran beautiful damn it I ran it into a shed wall and now it surges like crazy. I've taken the carburetor off and cleaned it out but it still surges. I think I may have been the governor Rod but each time I touch it or bend it a little, it races really high. anybody know how to the rebend or adjust the governor Rod? If you have any other ideas let me know.
