Take the float off. shake it. does it sound like there's gas in it? If so, It is bad. If your plug is getting soaked with gas, it is most likely either the float or the needle, or both.

Hello: Spanky

If you rebuilt the carb, are you sure the fuel adjustment screws are set to the orginal settings? If the plug is getting wet, could be the fuel screws are set incorrectly.

As mentioned by cheese, the float could be damaged or have a pin hole in it. Remove it and shake to verify if fuel is inside it. If so, it must be replaced.

Another possibility could be a leaky fuel needle seat. Did you replace that also? If so, be sure it's seated correctly and fully. If it was not replaced, replace it.

The float level must also be set. When the carb body is upside down and the float, needle and seat installed, the float must be level. If not, adjust the tab to make the float level.
