Anyone else experienced this problem?

Wayne,
Pretty common problem.What they recommended would be vent baffles not jet extensions on the secondary.
Baffles help with prevent the fuel from sloshing thru the vent in the carb throat.Causing the stalling problem during hard braking.
The Jet Extensions help to prevent fuel starvation in the secondaries from the jet becoming uncovered on hard acceleration.
