v-mad

I need some more help here. I am used to webers (28/36, 38DGAS etc) and with those you can select jets for idle/progression separately from the main jet. On the Holley, there seems to be no option to jet separately for progression mixture.

I have already set the idle mixture screw for fastest idle, and it sounds OK. I guess I could do better using an exhaust anyalyser if I had one!

Being a Holley novice, I was under the impression that the main jet also controls progression mixture. Apart from that I know there are adjustments to the accelerator pump system. Do I need to experiment with that to weaken the progression mixture?

I doubt that the power valve needs changing as I have a stock cam, but maybe I am wrong there?

Finally, I dont have a fuel pressure regulator, but looking into the venturis, there is no sign of flooding so I dont think there is excessive pressure.
