Many of us have been Model A owners for decades and decades, and we're STILL educating ourselves. There is no end to learning. Keep reading up on your car and following the advice of the knowledgeable guys on this website. It's a stiff learning curve, but little by little through practical experience and reading you will gain a proficiency to handle most problems that will creep up. Don't get discouraged. 95% of potential problems can be solved by owners after a little thought and research. It's the other 5% that will require professional help, such as from an automotive machine shop. The odds are in your favor to successfully make necessary repairs. Look how far you have come since you posted your first question here!
