carb gods help please
 

I am new to the carb thing and don't know much about them so I could use some help. I bought a "Holley 750cfm HP with mechanical secondaries tuned by Reed's performance" from Ebay. After looking the carb over I noticed that the airbleeds have been removed, and two holes have been drilled on the front throtal plates. Why would they do this, and will this thing even idle like this?
What do "screw in air bleeds" do anyways, and what is the point of them? Also on the metering blocks there is two screws... what do they do? There is also a number wrote in marker on top of the fuel bowls. I think it said 58 but I know for sure it was ?8. What would that number mean?

Thanks,

Air bleeds atomize the fuel before it hits the barrel. Having "screw in" air bleeds allow you to change the atomization of the fuel.

The two holes in the throttle plate are there to help the idle on the existing car, think of those like and IAC solenoid on an EFI car.

The two numbers on the bowl are the jet sizes that are in the carb.

They took the air bleeds out completly. They didn't drill them out or anything because I can see the threds. IS this a normal thing when they tune a carb?
Also, what about the screws on the sides of the metering blocks? What do they do?

Thanks,

Idle mixture. I believe i posted a thread in the Tech Tips forum at RHC that tells you how to adjust them properly. If it's not there, hit me up later and I'll walk you through it all. Carbs are easy.
