Yep sounds like a bit of emulsified oil. If you're in the habit of wiping down your airbox with an oily rag or giving it a bit of a spray with wd40 it tends to gather there. I've just cleaned some out my airbox this morning! I'm about to give the carbs a good fettle this weekend once I feel confident enough, was it running lumpy? I'll let you know If I find the same in the carbs.
Treat everything in life the way a dog would- if you can't eat it or foc it, forget it.
