My old Briggs data for Model 28's shows a 16 pound crankshaft as a part number and two styles of cranks that weigh about half of that. The heavy doesn't have a syncro-balancer and the other two are the removable and non removable eccentrics with syncro-balance. What year? I have no idea. I too have never seen one of the heavy ones.

  
Check this out;

http://en.wikipedia.org/wiki/Briggs_%26_Stratton

The Synchro-Balanced Engine - This 1966 innovation was designed to attenuate vibration caused by the reciprocating mass of a single-cylinder engine. The design was a series of counterweights opposing the crankpin.[10]

FOR THE MOST PART THEY DID THIS BECAUSE IT WAS CHEAPER THAN BALANCING THEM LIKE THEY DID IN THE 1.5-8 HORSE POWER ENGINES. IT ALSO MENT WE CAN MAKE MORE AND SELL EM CHEAPER THAN THE COMPITION.
