Why is it dying?

Believe it or not I actually had a internal battery short that caused me all kinds of trouble Not saying this is your problem very unlikely but it does happen.

Battery is an Optima Red Top and only about six months old, but Murphy's Law being what it is, it's certainly not impossible.

How about the rear float level a fraction high, and flooding the engine on decel?
Drop the level by 2 flats at a time, and retest.

Good idea. I'll try that before switching to the loaner carb.

If the engine doesn't stop under hard braking, that rules out the usual suspects like float level and fuel sloshing from the vent whistles. That is why I asked that question earlier.

It is most likely that you have the idle set to high....with the idle screw that adjust the plates.......set the throttle plates first.....they should just uncover the transition slot.....and then you are supposed to adjust the idle via the idle screws .... The main idle ...screw ...is know used to get it final......if the idle mixture and transition circuit is set correctly it will not do that......1100-1200 is too high...it should still idle under 1000.
