REFLECTOR: Fixed Pitch prop on IO520

Typically you insert a plug in the end of the crank shaft, this is the 
supply/dump port for the CS prop.  If you don't have a CS prop you probably 
have the plug installed. If not I'd think you be oiling the world with 
every flight!

I figured I would need to put a plate over the gov pad and possibly a plug 
in the crank though I can't find it in my parts manual,
I wonder if I should leave out the bevel gov drive gear and some other parts?

Can't guess on this kind of mod, or you might end up trashing a $40K engine!
