Congratulations Tracy on the two safe flights so far.  I think we all have a
vested interested in your keeping the flights this way.

My 13B is harder to start turning and keep turning with the prop when it is
warm compared to cold.  This is felt when compression isn't adding to the
load.  The additional load due to compression seems more with the cold
engine compared to when it is hot.  In other words, the coefficients of
static and dynamic friction increase when my engine is hot while the
compression load seems to decrease.  My experience is limited to just my one
engine.
