     Were you referring to Bob's 5hp compressor motor ? I'd check mine but   
   the data plate is on the back side and the unit is in a pretty tight spot .

   I've just got the one for the tiller , there's another out in my pil o'   
   stuff on a busted tiller that was said to run when the guy gave it to be   
   . Oh , and an old B&S probably 3 hp side valve down i Memphis . Doubt   
   that one will even turn over , the kids* "needed room in the shed" so   
   you know where the motor landed . At least it was still right side up   
   last time I looked .
