Also what color spring is in the secondary's since you have a stock engine and ignition you can't get to aggressive with the secondary's .
Have you checked the float levels
I set the primary just below the hole and the secondary just above the hole. And Holley carbs should run 7 psi fuel pressure they are not like Holley 94's or Strombergs they will take the fuel pressure!!

Right now I have both float levels set at the hole. I'm not sure on the spring. I haven't got that far yet! I'll have to open it up. I can adjust the fuel pressure up, I'm at 6 now.
Thanks!
