Help with flow on Carburetor?

[claywade]

Hello, I was wondering if there is a way that I can modify my Edlebrock 600cfm carb to flow the same amount of air but only 5 to 10 percent of fuel? I am researching a lean condition and need to flow a very minute amount of fuel. Thank you for your time.

You could try a main jet with only 10% of the cross sectional area (CSA)of the original, and plug the idle and transfer circuit restrictions and re drill them at 10% CSA.

Also do this for the air bleeds.

Why not use a Webber as they have much greater adjustability.

Either way, the engine won't run on 10% of required fuel.

Regards
