I agree. I believe what is being sold is a "easy and complete solution". In reality, it is someone else's opinion as to what will make the carburetor perform better. The kit will very likely make the carburetor work differently, but I'm not so sure it is always (or even often), better. Like you, I would rather have my own set of jets and understand what I am doing with each one as I change each variable individually.
