replacing my old briggs and stratton CARBURETOR with the new one

[Cshawl21]

hi i was wondering if anyone knows if the new Briggs and Stratton Carburetor 499491 is better than the old on Briggs and Stratton 499952. Because the Briggs & Stratton Engine i have now is a, it is being used as an Edger i have, but the carburetor is so old i am thinking about possibly upgrading it to the new version of it. So if anyone knows about the new Carburetor could some one please tell me. Thanks
