There, at the base of the Weber 40's, at the base of the passenger side carb throat was wet with gas. Huh? Engine has not run in two weeks.

Could it be a drip from above? (after sitting for two weeks??)

Versus the Driver side carb which was dry of gas at same location:

There's no constant drip, just wetness at the indicated areas that are giving off the fumes that will get me evicted from inside storage.
Larger view,
thanks

I always had trouble getting my Dellortos sealed to the intake manifold, and got gas running down my manifolds. That's what I get for polishing my manifolds...

Did you polish the mating surfaces with sandpaper on glass?

No, I did not polish or mess with the manifolds in any way.
Can anyone advise me as to why there would be gas here without the car running for over two weeks?
thanks for your comments.

Webers have freeze plugs which will weep fuel when they are failing. That could be your issue.

I used to wonder why mine had epoxy on the plugs. A year after I cleaned the carbs and the epoxy came off I noticed the leak. The plugs are on the engine side of the carbs. From there the fuel can dribble down the manifolds to the heads.

Have you even considered the possibility that the carbs leak? They do that, you know. Or maybe you don't. With astonishing regularity.

They're not really freeze plugs but...
We routinely take them out and replace them with threaded plugs. I've seen too many fall out and dump fuel all over.

checked your float settings and needle valves lately?
Dirty needle valve that wont close will just let gas in till it overlflows the bowl...
poorly set floats do the same thing, and most floats are wrong that I have seen.

+1 On the small lead plugs in the sides of the float bowls.

Had 2 come out at Watkins Glenn about 22 years ago. As luck would have it, the guy in the next garage stall actually had some new ones. Staked the new ones in and problem was solved.

This is something I need to do to my 40s before I install your linkage. Gould you give me a parts list of things I need to do the job? It is as simple as an NPT tap and the correct sized plug?

Not NPT. 3/8-24 stainless set screws, permanently retained and sealed with red loctite.
