Yep, i too would say u are a little rich, in which its obviously better to be just a bit on the richer side than too much on the lean side for obvious reasons. That sludge is probably just residual fuel/oil being left behind by the combustion process....

make sure ur glow plug is tight. Maybe clean i t up and throw in a new one or washer at least.
