Are you placing a dab of locktight on the valves lock nut/key?
Could your cam be bad? Could you be wearing down the lobes? This is rare but happens. Are you sure the lock key is backing out on the valve adjustment?
I haven't played much under the hood of the F23A, does it use a hydrolic lifter for the cam to valve action? Don't have my manual handy. Could you be loosing pressure to the lifters if they do have them? My mechanical lifter Dart needed adjustments all the time--but the invention of hydrolic lifters fixed this?
