After years of using Hollys on a crossram you have only one problem- Lean- The idle circuit has to be rich or it will bog or stumble, wiil the engine idle 600 rpm in gear? The secondary's have to be shut with no light visalble around them, adjust the little screw on the base plate bottom. Main air bleeds small .0018 main fuel bleeds large .070 a good place to start. If right, squirters are not needed and if you push pedal down alot you're out of there range anyway. Any vacuum leak is you're enemy 8 is enough. Hope this helps
