The float level is set by moving the collar on the needle up or down. To lower the fuel level, the collar needs to move up the needle, to raise the float level, the collar has to move down the needle. If it's an original needle, the collar will have been soldered to the needle. In the case of a flooding carburettor, the Zenith instruction book says "....unsolder the collar on the float needle and move it a shade further from the point". Rather than unsoldering, I've moved the collar up the needle by holding the needle in aluminium jaws in the vice and using a length of suitable tube, gently tapped the collar down "a shade". It's worked fine for me a number of times but do it at your own risk!!
If nothing else has changed, it is most likely that the initial cause of your problem is that your replacement washer is not the same thickness as the original and if you were to remedy that, the problem may well go away.

Edited to add: Of course, the checks that Howard lists above are the obvious starting point before trying to adjust anything.
