I find the Holley to be simple enough until it isn't. The jetting is a matter of testing or just driving. The accelerator pump is a static adjustment but you can tweak it. And the idle screws and speed could not be easier.

The power valve is something to reckon with if you are out in left field with your carb. If you have to change out the PV for some reason I think it's better to work with a pro using a dyno.

So really, these girls are performing a cosmetic service that a tuner with a dyno may not want to hassle with. Bring a nice clean carb with new gaskets and the tuner can get to work.

Right, there's only so much that you do when rebuilding a carb if someone hands you a carb; clean, change gaskets and parts for new where required, set the things that can be set statically, and then hand the carb back. Tuning things that need to be tuned based on the engine that the carb is bolted to is not part of a rebuild, it's tuning.
