My dad will be able to help me a lot on this project. He is a car mechanic and works on cars everyday. He might not know a ton about go karts, but he will know different tricks and techniques that can improve the fixing of the kart.
My dad and I have a really good relationship. We are always working together at the track, and have the same interests in cars, racing, and mechanics. he will be willing to help me and show me ways to fix cars or go karts more efficiently. He also knows how the engine works and will be able to help me understand it better.
