You bring up an interresting point with the carb heat. Putting on the heat will richen your mixture. Back when I was having a bunch of problems with my Zenith carb and I had my mixture meter I would put on some carb heat at times when I needed to richen the mixture. You would be surprised how much it richenes it. The lesson to be learned is that if at any time you find that your engine is running a little smoother with some carb heat on your mixture is too lean.

I discovered that (at least with my engine set up) that there is a real sweet spot in the mixture setting on the aerocarb. The biggest signal that I got when I found it was how much smoother the engine got. The noise (read vibration) that has been bothering me for months was turned into this beautiful hum. The exhaust temp that it smooths out at is about 1325 deg and any change in throttle setting up set the balance of things. It did not take only 100 rpm change to need a adjustment in mixture. I also had just a tiny bit of carb heat on and I could tell the difference with and with out that too. There was a fair amount of haze in the air tonight. What a wonderful flying machine it was tonight. A couple landings at different airports with cross wind of about 20 deg at all. I did get a tad of side loads on the mains on the first touch down but was able to correct it easily. The landings are getting better each time, a well as speed and decent control. The flying is becoming much more enjoyable because I'm not just staying up because was afraid to land. Maybe I can sneak in 1 more flight in the morning before the big snow storm.
