Dry powedery carbon is a sign of over fueling due to impared air intake (more often than not), so that's prime candidate.

As YC says though, check that it's not constantly "cold idling" - on the K7/K8 this is easy, not so previous to that. Easiest way I can think of is to fire it up with the air filter removed, and watch for the butterflies rotating when it's warmed enough.

Or you could use the temp sensor (look for the wires leading to the rad (top right corner IIRC)). Check it's working properly by testing resistance. But I'd just watch for the butterflies opening a little more & the revs dropping. That'll tell you the "choke" aint stuck.
