I’m confused on how to adjust the linkage on 2 4s. I assumed, which I now believe was wrong, that you adjust idle on the primary carb only and adjust the linkage so that the secondary carb only opens when you open the secondaries on the primary carb. I believe that is wrong but would someone please clarify for me. And do you recommend the Edelbrock dual quad linkage. Thanks in advance for the info
