Either that or ther is some debris stuck in the float needle seat.

The most common error is to put the floats back either upside down or with the little pips that operate the float arm, on the wrong side of the arm. That is, underneath the arms when the carb is inverted.

Remove the throttle slide assembly by unscrewing it from the top of the carb.

Remove the fuel line and then remove the carb from the air box and collar.

Empty the excess fuel into a dish by inverting the carb.

Shake the carb and you should hear the floats rattling.

With the carb upside down on the bench, remove the three screws from the float bowl.

Lift off the float bowl carefully in case the gasket has stuck, check the gasket for damage.

Are the float pips sitting on the top of the arms?

If not, this is your fault.

Take the floats out and shake them to make sure they haven't punctured and filled with fuel.

Replace the floats and carefully fit the float chamber back.

Refit the carb and test.

If it still floods, there is a problem with the float needle or arm.

This is easy to check if you restrip the carb and disassemble the float arm by pulling out the fulcrum pin and lifting out the needle. Clean it's tip and seat with carb cleaner or brake cleaner and reassemble.

Check the fuel filter under the 12mm nut while you have it on the bench.
