[DeTomaso] Great new brakes, but stalling when braking

[bill gaino]

Mikael, have you tried a "slosh tube"?  Cut a piece of fuel line and stick it on each vent tube.  Some carbs have longer vent tubes, always keep an eye out for them and aquire when you find them.This will form an arch over the carb. Now cut a hole in the top of the tube to let air in. The idea is that the fuel will slosh to the front bowl rather than dump into the carb opening and flood. We used this simple setup drag racing.  Try that.  Bill 1362
