Default Primary carb- Front or back?

Since my last post, I found two problems. A sticky valve (MMO works!) and a bad condenser. Running better but still backfiring through exhaust a little. Advanced Dist. about as far as it will go, vacuum brake working fine, no leak.

My question is- on a regular dual intake, running two 94's w/ progressive linkage, front primary w/ 51 jets and a 3.5 power valve, rear is secondary without idle mix screws, .048 jets, no power valve (plugged). Which works or runs better, having the front carb as primary or the rear? Easier to get at idle screws if primary on rear, but any other differences? Thanks again!
