Sputtering

[BoxyBuffalo123]

I rode to the gym and everything was fine, after around 1 and a half hours came out and started riding and all of a sudden it started sputtering and spitting the more I accelerate but it idles fine and sparx looks fine? And I doubt it would be the main jet because its been riding fine for a month and the carb is a few weeks old, I wonder if its a fuel filter but I'm not sure where it is
