Rick,

Something does not sound right here.  Most of the engines that I know of have 
either a split hub on the flywheel to tighten a bolt and uses a square key, 
or they have a taper keyway in the hub and flat keyway in the crank and use a 
tapered key.  I think there may have been a few small engines that used a 
square key and a set screw in the hub of the flywheel to hold it in place. The 
crank keyway was never tapered, only in the flywheel hub. I would do some more 
checking and be very careful of driving in a square key.  If the square key 
tightens up driving it in, it says that the keyway surfaces are not parallel, and 
therefore must be tapered.  You are only talking about .012 taper per inch of 
keyway length.
