Low CHT

      Hey friends.  I have a low time M-14P on my Nanchang.  I typically have low CHTs
      in the 140C range even with gills closed.  Fly out of SoCal so not a cold climate.
      I know Richard Goode tends to point to the suction jet and being too rich,
      but know that I also only get around 35gph fuel flow with WOT. I have increased
      the suction jet as large as I can to raise temps but not get a lean surge
      at altitude.
      Thoughts?

      Hello Gil,
      
      Interesting. To be honest I would first suspect the sender underneath the
      spark plug. It is a very imprecise way of temperature measurement that can
      be helped by rarely cleaning the cylinder head and the sending ring itself.
      And then which suction jet have you got fitted? And the engine as a standard
      M 14 P?
      
      Please let me know and with regards
      
      Richard
