Plug is out and is not oily or wet. Also, the blade does not turn
either. I should have mentioned that. You can not turn the blade,
pull the cord when fully assembled, or manually turn the flywheel or
cup that attaches it to the crankshaft.

The oil is just above the fill line. So, it is about time to add more
oil, but the oil is not low (as in not below the fill line).
