NOW, it sounds like BoB has the right idea of it being the Accelerator Pump or Pumps, is it a 'Double Pumper'? Have you actually checked to see if you are getting a 'Good' squirt of fuel when you open the blades, both on the Primaries AND Secondaries? Are your squirter noozles big enough, or TOO big. As BoB suggested; are the Acc. Pump Cams correct and is the 'Spring' adjusted properly? You know, once in the past, years ago, I made the mistake of getting the METERING BLOCK Gasket (OLD design) in backwards, This will BLOCK the Accelerator Pump Passage. I have noticed that the NEW design gaskets now have the 'hole' on both sides of the gasket to make this mistake 'foolproof'. This last entry would be if the problem was NOT enough Gas. On the point of there being TOO much fuel going in: There are two possiblities, that you have one or two 'Power Valves' that are too weak, and are opening too soon, flooding the card(If your carb is a 'Race Only' then your secondaries have NO power valve and are delivering EXTRA fuel 100% of the time). Second: If you have mechanical Secondaries, they may be opening TOO soon. And if you have Vacuum Secondaries, the spring may be TOO weak, and is allowing the Sec's to open too soon. You might pick youself up one of the many books about Holley carbs, they all have a detailed troubleshooting section. Stick with it, you will find the problem!! Regards, Marlin.
