Jim,  me thinks you might be off by a decimal place or two in your rate of climb increase figures.  I figure an additional 33 fpm (total 1033fpm) with a 2hp increase.
 
Also just a theory

True.  But that 2% increase in power is ALL EXCESS THRUST (over and above what it takes to hold exactly what you've got - say 90 kts and 1000 fpm climb).  Two hp would be 66000 #'/min which with a 2000# airplane produces 3300 fpm rate of climb - ABOVE what you started with !!  Just a theory ....
