Pull out the in tank fuel filter and run something the same size as the outlet nipple,,,there is a casting mold problem with the fuel tank outlet nipple restriction ,,,you will be able to feel it pop threw,,,I used a dremel bit itself seemed to be the same size as the original hole,,,when the tank is empty take the cap off and blow threw it to judge how restricted it is,,,,and put on a external filter but make sure the filter not lower then the carburetor,,,then you will be a Happy cub Cadet Owner,,,instead of a pistol off one,,,trust me I know,,,,,
