Weber Leak

Before I, or I have someone else, tear into this - any idea what the leak on the right might be caused by? The gaskets have always wicked gas since I installed the carb, but this seems a larger issue. I've read various things that say gaskets can be damp, some say they shouldn't be at all. Any insights would be appreciated!

Is the mating surface clean and knick free under both gaskets? I would suspect either a warped flange, or a faulty sealing surface on the intake manifold or carb. I wouldn't be comfortable with gas seeping out. I would clean the gas off of the carb, check the flanges and make sure they're true, clean, and free of any markings, and install new gaskets and see what happens.

I'm wondering if it is leaking around the throttle shaft.

I noticed that, too, after closer inspection. Leads me to believe there may be an internal leak, which is allowing fuel to run into the intake.

then I would check the float level. If its too high it could be your issue.
