When setting the float level the Daytona valves use a different technique versus the OEM valve.

To achieve the correct float level with an OEM needle and seat a tang on the float is bent/adjusted.

For the Daytona valve the float level is set by shimming the seat with more gaskets. At the closed position the tang on the float should contact the Daytona needle as close to the center as possible. If the tag presses off center by a significant amount there is a possibility the needle will be pushed into a cocked position that will be beyond the capability of the compliant flat disk. Daytona covers this in the instruction set, and if you follow the instructions the valve will work as advertised.

Shimming the seat of the fuel shut-off valve to achieve the correct float level is not a new invention, it goes back something like 100 years.
