Too dark for picture. Looks like gov spring at bottom is hitting the fuel line?? At times just putting the cable outer housing in diff position on it's clamp allows more movement. You change anything recently that makes it not work now.....say that fuel line that looks new? Books might show the proper holes for the spring to be in and other end with linkage might have more holes, can't see. Gov can be re-adjusted at it's shaft and mount, but if hasn't been apart or loose lately, don't think that should change.
