Thanks for the replies and tips, guys. I sure do appreciate it.
Here's a pic of my A4, and the tight confines I'm dealing with on the manifold side. I'm not sure if I can make an access panel, because frankly I'm not sure what's behind the fiberglass opposite the carb. I'll have to go down into the aft port locker where the fuel tank battery charger and wiring panels live. I might be able to squeeze in there and find what's just beyond the exhaust.
Permatex #1, check.
Shouldn't the (Edit: thanks ndutton!)
flame arrestor prevent the fuel from spilling out if I have a float valve stuck?
If I go ahead and remove the carb, will it be readily apparent if the float valve is clogged?
For bonus points, can anyone tell me what that thing is that's sticking out the front, just below and to the right of the thermostat?
