Needing some help.

[Mafort]

So I’ve got an American elm stave. Perfectly clean and flat back and belly. I want 70-75@28” of draw. How thick should the limbs be?

[Jakesnyder]

How long is it going to be? What's the design of it? How wide are the limbs?

[Mafort]

66inches long an American flat bow design and it’s about 1.5-1.75 wide

Thick enough to give you the poundage you want, sounds like a smarty pants answer but you won't know until you start removing wood. This is why we floor tiller, every piece of wood is different. If you start with 3/4" thick limbs you will have plenty of wood to meet your poundage goals.

"Thick enough to give you the poundage you want"  Amen!!!

Yep!  That is a definite maybe!  !  As I said before - it is easier to take wood off than to put it back on!
