problem with a /6 carb..

I am doing an engine upgrade soon so I really don't want to spend any money on the slant 6...it has had a hesitation when excellerating when cold ..I can live with that but my daughter tookme out for a drive nd when she turns cornes, it dies..then picks back up once she straightens up..

I think this is more serious. I think it is the carb float..do they have those on the /6 carb. Can I change it and how or do I need my racing mechanic guru /

Should I have posted this in the barb section ?

Thanks
