what, if any, would making the secondary throat open mechanically rather than by vacumn acchieve. would it cause flooding at low revs?

Vac Sec
Opening the secondary/s by vacuum is the best way for a manual equipped vehicle. As manifold vacuum increases sec's are pulled open. If you modify yours or fit mech sec the engine will use more fuel and bog down when you accelerate. Opening both barrels at low engine speed causes very low vacuum signals in the carb and poor mixtures result, until revs increase significantly.
most autos are mech sec .............. mostmanuals are vac sec.
