The orifice [ 0.060"]   is THE  Positive Crankcase Vent    there is no 
checkvalve!  It's not needed due to the long balance tube.

The size was "standard"  and usually adequate.....but can be enlarged 
slightly without affecting idle quality ...... if you run at higher RPMS  for great 
lengths of time.
