The enricheners are what you have circled. When the motor is cold, these act as chokes. Also, the vents on the carbs are holes that you will not be able to see while mounted on the intake manifold, but will leak some fuel when the engine is tilted. You can also get fuel that will leak out of the carb throat, and move into the silencer. The silencer will also have some crankcase residue from the breather, which is vaporized oil and gas as the engine warms up and the breather recycles the vapors into the engine. This will make any fluids that exit the breather be a gas/oil/water vapor mixture -- dirty looking, gas smelling residue. All natural and mostly non-issues, unless it becomes extreme. You can reach the bottom carb drain fairly easily with a small box-end wrench. It only needs to be cracked open slightly to drain the carb. Do not worry about what you have seen -- you are just being extremely aware of something most others would not even notice. :smile Ron
Gas dripping out of engine...right before Powell trip, too.

Bob: Thanks for the time-frame reference on carb draining vs. not - it's good to have a baseline idea.
tsturm: Appreciate the confirmation on the drain screws and the "thing that takes the place of the choke."
So, if I understand it:
a) choke (which I don't have)
Restricts the air intake to richen things up.
b) "thing that takes the place of a choke"
Probably adds fuel to richen things up.
So two different means of achieving the same end, apparently. I think my Honda 8D also uses method b, whereas the old standby Honda8A uses the traditional choke. Anyway now I know what the "schnozzles" are for.

Ron:
Aha, I think you've hit the nail on the head - that makes perfect sense as to why the fuel would definitely smell like gas, but also be "thicker" and behave more like oil. Also, the path did seem to follow straight down from the grille that I think is the air intake - sounds like it's the silencer (maybe they are one and the same). It's great to have a handle on what was most likely happening!
I started to worry that my post might have been a bit too much of an over-reaction, but you know, I've learned so much from reading your replies and looking around the engine since yesterday, that I'm glad I tilted it up all the way and had the "leak." And maybe a few others have found the thread useful (or will).
Also good to know that carb #4 will not be as bad as it looks :thup
