- 1968 corvette bronze coupe
My 68 327 has a referbed quadrajet on it. My mechanic had this thing set to idle at 600 rpm. I want to adjust it to idle at the proper 750 rpm. I understand there are 2 idle speed screws, the base idle screw and the fast idle screw. I'm familiar with Holley carbs but the quadrajet is confusing. How do i set the proper idle on this carb?
