Backfiring into the TB can lead to this. Actually this is the only thing I can imagine that gets carbon buildup inside there:) Didn't your mate notice backfiring into the airbox / cutouts / farts? :)

Anyway.. check the seating of that TB (look for a torn boot) and if the vac. ports on the intakes are OK. (no torn vac. hoses for example)
