You may want to consider replacing the isoblock, gaskets and carb retaining screws. The screws as well as the nuts embedded in the isoblock may have some wear on them from vibration. When reassembling, use blue loctite. Check to see how loose the screws are when turned into the isoblock.
Same page. The long screws that retain the air horn and carb screw into two nuts cast into the isoblock. Turn them into the isoblock with the carb off and check for looseness then make a determination. If they are continually loosening on their own, it seems fairly obvious that there has to be some wear, either in the carb retaining screws, the embedded nut or possibly both.
