1993 OMC 3.0 Cobra, Holley 2300 Carb problem

[medicwithboat]

We rebuilt the Holley 2300 carburetor in August and the motor ran better than it has since I acquired the boat. It was winterized in December by my local servicer. While doing some work on the back seats, I noticed what appeared to be a liquid oozing out of the seal between the main body of the carb and the mounting base. It smells like gas.

With the boat having been sat up for two months, how can this be? If I understand things correctly, there is no fuel held in the carb except for what might be left in the fuel bowl. All seals around it are dry.

Any ideas?

maybe some gasoline incompatible sealant or gasket was used there, and the gas reacted with it. softening it. Maybe it was an old rebuild kit pre- methanol.
