Hi, Terry.
I'd suggest first looking for a needle valve blocked open by debris.
Since the flooding started suddenly, it suggests a sudden failure of
some sort. The other possibility that comes to mind is a broken fuel
pump spring, if you have a mechanical pump. The broken spring will
cause the pump to deliver fuel at a higher pressure, but it won't be
able to deliver as much. At idle or part load, it would still be able
to deliver sufficient fuel, but the excess pressure would force that
fuel past the needle valve and into the carb.
Hope this helps.
Donald.
