      Hi Jack,
      
      Your cht should be working and the cht raises quickly. So if it's not working check
      your connections. Set the idle on your new engine between 1750-1800 rpm.
      140F on the oil temp at idle is probably about right. You should see 120F or above
      before take off. 266F cht temp. is max for the 912uls. Each engine differs
      some and so does each person's gages. Hopefully your oil temp. will be between
      190F-230F when you are at cruise rpm. 
      Cruise rpm should be between 4800-5200 rpm. This is it's best torque and the engine
      should run cooler.

      CHT's running 100 degrees F ????   That does not make any sense at all.  That is
      very close to the reading you would get with a completely cold engine.   Something
      wrong in your readings, or in your reporting of temperatures.  A CHT 100
      degrees for a running engine is impossible.
