BEFORE you open your carb, turn the inline fuel switch to off, then remove the gas line at the carb to see if it is leaking with the switch off.
Always do the least invasive things first.

since your bike runs well after you clear the flooding, I would suspect the carb only after I had eliminated everything else.

However keep in mind I'm the guy who seized his engine before I really got it to run so take it with a grain of salt.
