I guess a crude analogy would be childbirth. It's expensive to birth
a child in a hospital, with an MD, nurses, and all the diagnostic
equipment, but if there's ANYTHING out of the ordinary, you'd be glad
you paid the extra money. I'm sure there are some carbs that are in
good enough shape to be rebuilt just by buying the kit and replacing
parts, but unless you have the experience to know that, and to
know that you're reassembling it correctly, your best efforts might
be all for naught.
