Carburetors for STR-12 Manifold

I install two spring loaded burst plates on my bigger manifolds (tunnel ram, big single plane etc). The need to be adequately sized unlike some of the postage stamp sized units contained in a spacer.

If it was me I would be running something with annular boosters and a relatively lean transition/cruise AFR and a tad rich idle AFR. It seems to help .

Not a fan of the Brawler carbs OOTB.
