Well, the vent tube idea really didn't do much. I then went to Eurocarb and ordered these "surge washers". They seem to help but still not what it should be. I still have and empty float bowl doing hard cornering.
The idea is that these washer cups sit just at the bottom of the float bowl and prevent fuel from sloshing up the side of the bowl or not let all the fuel do that. Some should stay in the sump nut where the jet is located. This seems to be a common problem from my research but no one had found a fix other than changing to fuel injection.
