He is smelling unburnt fuel and the injectors have been checked I think. I might even want to do a compression check on that cylinder before going on to checking it for proper load sharing. I just went back through the thread and see that compression was good and fairly even. So I would move on to check for load sharing by the third cylinder.
Cylinder 3 was the only one that seemed normal out of the 5. The other 4 had severe carbon build up on the heat shields. If running WMO was the cause, I would expect to see all 5 injector shields in the same condition. If the timing is retarded, I would also expect to see all 5 in the same condition as well. I think I should check the injection timing next. If the timing is too retarded, I would expect excess carbon build up and WMO would make it worse than usual.
