If you are experiencing this problem at around 65% of your throttle then you are having what is reffered to as Lean Bog.
The Carter (Edelbrock) is designed so that at 65% of your primaries the secondaries start to open. Both the primaries and secondaries should reach wide open at the same time. If not then adjust the shoe on the linkage to your secondaries to correct this.
To check for lean bog drive your car around at high rpm varing between your bog range and WOT. Then shut down without going to idle and pull a plug and look at it. I know it sounds weird but it works. Pick somewhere the counties wont bother ya.
If the plug is white and not brown or light brown then you have the lean bog problem.
To correct it go a step at a time bigger on your secondary jets.
That should fix your bog and jet your secondaries correctly.
Remember that going a bit rich on them will be better than lean.
