It appears you are trying to adjust the carb to correct a problem.
Tell us the problem you are having and perhaps some suggestions as to where to look can be offered.
But Frank is correct. There may be a part of the carb that functions as an idle air control valve (just as there are parts of a fuel injection system that can be explained/related to in carburetor terms) but there is no IACV to adjust. There are many other adjustments and corrections that are possible, but we have to know what type of problem you are trying to correct to go any further.
