bought a 212 last year for the deck , cause someone stole the 110's deck while I had it apart welding radius plates in . the deck just barely fits under the 110 , and it needs a rebuild 1/16 qt oil per mowing burnt . so I decided to get the 212 going , took the carb off cleaned it set the points , got spark . when I crank it it spins rather fast and there is no noticeable suction at the carb . no bad noise or scraping , the valves are working . I' guessing a blown head gasket ? I gave $200 for it , worth it for the deck alone.
