     John,
     
        Does it sling the oil from a gallery in the crank?  The crank 
     counterweight does sit about 4 inches lower than the center of the 
     crankshaft.  Doesn't the 3.xx" stroke then allow the counterweight 
     on the crank to touch the reservoir?  How does it THROW oil spray?

Umm Joel,

I could have sworn I read somewhere that (with the exception of small 
engines lacking a pressurized lubrication system, ie. Briggs & Stratton 
lawn mower engines) the crankshaft sprays or slings oil onto the cylinder 
walls.
     
From CTS-2130-K in the IH shop bible (Old International Version)...
     
"Pistons, piston rings and piston pins receive lubrication from oil spray 
THROWN from the engine crankshaft.  The connecting rods on the engines are 
not drilled for oil channels."
