I wonder if we're comparing apples to apples. I think Kawasaki is the only brand using the corrected hp rating. In other words, a Kawasaki 31 hp is 31 hp or at least very close. A Briggs or Kohler, still using old 20% off hp rating, 31 hp may actually only be a 28 hp which could explain the better gph? From my experience I would say this is the case for Kohler. I don't know about Briggs. The Vanguard I have on my Z Spray and all the threads I read seem to make me think the Briggs are using the newer hp rating. They seem pretty powerful.
