I don't know where to find the engine, but I can tell you a quick way
to tell which way to turn the nut to loosen it:

carefully pull the start cord on the engine and note which way the
shaft turns (may need a helper so one can watch and the other person
can pull the cord). The nut/shaft will be threaded so that the shaft
rotation tightens the nut (otherwise the lawnmower would throw the
blades off every time you started it up).

OK, thanks (to both of you). :-)
