The incoming air is just too cold, then it accelerates in the carb throat, and then no heat in the intake, so it never properly mixes.
I went to a class lycoming gave when I was visiting in Cal. One of the things they told use, when it is cold below 50* was to pull the carb heat out until you see a drop in RPMs and then push until it picks back up. After that adjust the mixture again. When coming home I climbed to 13500 did what they said and saved another gal.an hour,plus the engine ran smoother. Try it sometime. --- Colin Rainey <brokerpi...@bellsouth.net> wrote: __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
