But the 'primaries' (in the secondary location) are firing.

The issue comes to the fuel injection blending going on. When you floor gas the 'primaries' in the secondary location are unable to keep up with the air flow thus stalling out the engine. However you can creep up the RPM range if you don't floor it as the injection doesn't get 'out-flown'.
