Actually, that is a better initial approach. Try it out exactly as the factory designed it.

If after running a while, it doesn't work out, try the simplest "fixes" first. Ideally, you don't do any "permanent" modifications.

Usually, component replacements (power-valves, jets, accelerator-pump parts, etc) and adjustments are all that will be required to tailor the carb for your application, and oftentimes, right out of the box works just fine.
