Are you still driving a 1948 car? Sorry, but I can't understand why you would want to keep a 60+ year old toilet that is causing problems. You are wasting time and money on it not to mention the wasted water. You may or may not find parts for this old beast, but it just isn't worth it. I realize it's awfully easy to advise someone to spend money, but there just is a time that you have to face reality that things are obsolete.
