Black and wet indicates to me that the most likely cause is a bad spark
plug. Try switching plugs around and see if the problem follows the plug.
Or it could be the cap. Or maybe the plug wire. You could also try a
compression check to make sure compression is good on all cylinders.
The list is not moderated in the sense that posts have to be approved. But
their is a list owner and he has been known to ban people if they get too
far out of line (but I won't name names).
