Holley's science vs Edelbrock simplicity?

In all fairness, this notion "eddies work out of the box and hollies don't" just isn't right. I've bought new holley carbs and never had a single one that didn't bolt on and run real good right out of the box. The only difference is, with the holley you can fine tune good in to great (that last tenth at the strip you were talk'n about). Just because you have more tuning options with a Holley doesn't mean they don't run good out of the box. However, I've had eddies that couldn't get rid of a bog out of the hole, and not enough tuning features so I had to ditch the carb... for a holley and tuned the bog out.
I have two customers with ootb Holley's that work fine. And that's a good thing because beyond connecting fuel and a Direct Fit throttle cable they haven't a clue.
I teach them how to set the float and I show them how to set the idle and I show them how to adjust and set their choke and I show them how to adjust the air bleeds and for what reasons. I just tell them how the secondary spring works and how different Springs change how it works. I explained to them how the accelerator pump works and generally get that glazed look from them when I'm done explaining... it's information overload and they just want it to run good then pay me and drive off.... That amount of adjustability is wasted on most....
