I have thought this thru, and have a different opinion. First, assuming you have your float levels set right, if you have an aggressive, hot cam, and have a fairly low engine idle speed, at low rpm, idle, when you are braking, you are only running off the front primary side. The fuel flows to the front of the bowl, and depends on engine vacuum to pull it back thru the jets and into the boosters, and down into the intake.

I just think an aggressive cam allows enough vacuum at low rpm to do this. It just can't pull gas back and into the engine, hence the stall at low speed braking. On my car, if i make a slow speed sharp turn, like into a neighborhood street, the same thing happens, the gas flows to the side and my engine can't pull the gas back into the jets.

Long ago, i just started rocking my right foot over onto the throttle, just a bit, to keep my idle rpm up just a bit when i come to a stop or make a sharp turn at low speeds, i am no longer aware of doing it, i just have scuff marks on all my right foot shoes.

By the way, i have the vent whistles, and properly set floats, it is just in my opinion the above cause.
