Hy Brian_Ostner, I'm a retired mechanic (not a technician), and I'm the first to admit I don't know everything about vehicles and there components. I'm here to try and pass on what I have learned, so that others may enjoy the old vehicle hobby. I hope you stay with us and learn what we can and will teach you. Some of my fondest memories of my working years, were the times I worked with and trained apprentices, it gave me a great feeling to pass on what I could to them to help them gain their tradesmans qualification. Please give us another chance.
