That brings up another good tool in my flight testing box that I have used before. Pulling the carb heat will richen the mixture. If you ever find that your engine is running a little rough and pulling the mixture at all makes it worse your mixture might just be too lean. Try pulling the carb heat to richen it up and see if that helps.
I had to do this on my KR with the Zenith carb. Sure was nice to have a way to make my overly lean mixture richer until I could land and turn the mixture screw out a little.

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!
