    What worked 60 years ago in a REALLY badly seized Wisconsin VG4 on a   
   swather was about 16 oz of diesel fuel and an ounce of "oil of   
   wintergreen" purchaced from the local pharmacy. Pulled the plugs, put   
   about an ounce or so in each cyl and replaced the plugs. Let it sit   
   and add an ounce to each cyl every day for the next three days,   
   wiggling the crank a bit each day. By the 4th day the engine was freed   
   up enough to move. We then poured a couple ounces of MMO in the cyls   
   and cranked it over - chamged the oil, cleaned the carb, filed the   
   points and away it went, smoking like a fiend.
