What causes an idle problem on an Edelbrock car?
A fuel pressure regulator should solve the problem. An idle problem is typically caused by an air leak at the carburetor’s base gasket. The base gasket is located between the base of the carburetor and the intake manifold. To check for leaks, turn the engine on and lightly spray water around the base of the carburetor with a spray bottle.
Where are the floats on an Edelbrock carburetor located?
Edelbrock carburetors use two floats, both of which are located on the underside of the airhorn. There must be a distance of 7/16 inch between the top of the outer edge of each float at the air horn gasket. To adjust the float, bend the tab at the back of the float.

How does the idle adjustment screw affect the carburetor?
While tuning the idle adjustment screws I noticed that the right screw does not affect the engine idle at all when I run it all the way in until it seats. The left one greatly affects the idle when this is done, as it should. It idles fine, but hesitates under acceleration and under load.
