Need assistance with making adjustments to my carb (Holley 4 barrel 4160). I do have some images and text from the Internet on what to do. However, where do you hook up the vacuum gage to the carb for adjustment. I also read that the idle mixture adjustment is seated all the way in and backed out 1 turn. Is this a valid adjustment? Also the idle air adjusting screw not sure if my carb has that. See attachment
