Bob,
Me thinks you couldn't be more right :o(  Me thinks I couldn't be more embarrassed {{:<((  A bit off is one thing, off by an order of magnitude is another.  Forgot the sanity check and just flailed away at it.  So there has to be some other explanation why Ed's Mazda and my Lyc behave so much better on cold days.
Back to the drawing board ... Jim S.

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 theoryBob Darrah

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 ....
