i just went thru a 200es top end wise. in putting it all back together i was i tooth off on the timing. i had oilish smelling white smoke coming out the tail pipe. man ,,, i thought for sure i had a oil ring not seating for sure.
i was tickled to death to find that i was just off on the timing.
so anyways ,,, go thru the timing proceedure ,,, i hope that is all it is for you !

That sounds like the exact problem I had. I have a 200es and it turned plugs black in minute, and would no longer un after 10. The problem was weak spark, so it wouldnt spark every time it should, letting gas build up and run rich. The reason it was weak spark for me was the spark plug cable was old and the wrong type. I changedit and it ran perfect.
Hope this helps.
