Don't know what year it is, but with a Carter YF it may not matter. Remove the top and check the rod holding the float first. There is a dimple stamped into that rod maybe 1/8 inch from the end. That dimple must be installed toward the closest wall of the float bowl. Sometimes the rod will be installed with the dimple facing out into the float bowl and then the rod can slide out disabling the float (which lets your carburetor overfill constantly). If you installed the float rod correctly, please check the float to see if it has a leak. Usually shaking it will let you know. Also, if you bought a "one size fits all" kit and you used the needle and seat, I can promise you the diameter of the fuel inlet will be wrong. Please tell us the year of your engine and the model of your carburetor. It might be YF2101s, YF967s, YF3211s...something like that. With that information, we can help better.
