Carbon deposits are normal. It's strange to have a LOT of it though,
normally only certain parts of the engine (read: corners of
the combustion chamber) can support permanent carbon
deposits.
Any chance it's burned oil? Could be just oil leaking
in from the crankcase and burning messily on the pistons.
