A Holley problem all should know about and Why Holley Tech S#@KS

Watch the whole video an notice the primaries are really flowing and the secondaries trickle and are not even open. It then shows the problem. So this is vibration not pulsation. You would not believe the difference in the drivability in my Duster. I thought is was the cam giving it the choppiness up to 3500, it was fuel. I put my 115 , 125 jets back in and I even got to smaller air bleeds. It now smooths out at 3000.
