You're right, you do have a lucky brother, my dad was never a gearhead, and I was born with the "tinker" gene, he couldn't help me do much. I had to bumble through learning the whole car thing with a $50 buck, 1954 Ford I pulled out of a neighbor's yard. Your brother has no idea how fortunate he is to have a person like you to help him, and guide him through the tough spots. If he ever disrespects you just kick him right in the balls and show him this post.
