My 1925 T surging

This is embarrassing… When driving it in high it accelerates a little then decelerates a little … continuously. Any suggestions appreciated. Thanks

Welcome to the forum! When it decelerates, is it sudden, like a hiccup or cough? That can be a sign that the mixture is lean. Have you tried turning the mixture screw clockwise a little bit to see if the surging goes away? It won’t take much, maybe try 1/16 or less of a turn.
