El Dopa

El Bandito has started running on 3 cylinders.
The forth cylinder dropped out at the end (fortunately) of a 200K cobweb-clearing thrash, about 5k from home.
The first thing I noticed was the idle dropping to nothing as I cruised up to a set of lights.
I got home, and I've done some basic checks.
There is strong spark on the plug for that cylinder, and it doesn't look fouled at all. I've drained some fuel through the carb nipple and it doesn't seem blocked, or watery.
The plugs and battery are practically new.
As it started playing up suddenly, I'm inclined to think it ISN'T water in the fuel. The engine was hot, it was a warm day, and it had been fine for 200-odd K up to that point. All the other three cylinders are running fine.
So.....I'm thinking maybe some gunk in the carb? Does that sound like the most likely problem? Anything else I should be checking or doing?
