Hmmm, I would never have thought that you would get carb heat with the temp below freezing at sea level. I would have thought that at 6,000' that there would be no moisture left in the air to give you ice. Guess that is why they say you can get it at any time.

I goofed off till 8am before I started up N886MJ allowing the sun to start warming things up a bit. As I taxied out the temp was -1°C and the dewpoint was -2°C with the barometric at 30.60. For the winter, I have closed off the ram air and am sucking warm air from inside the cowl. I did my pre flight and called for clearance to take off. I climbed up to 6,000' rather quickly in the cold air. I was indicating a climb of 1900 fpm at 90mph indicated. Pretty nice climb rate but I do not think my VSI is exactly accurate. Anyway at about 20 minutes into the flight I started getting a rough engine. I quickly scanned the gauges and everything was normal except the rpm was fluctuating 50rpm or so and slowly decreasing. I reached over and pulled the carb heat and she immediately smoothed out and regained total rpm. Who says you don't need carb heat, I sure was glad I had it. BTW, my carb is an Ellison EFS-3A. The rest of the 1.2 hour flight was uneventful and beautiful. There was a lot of traffic at the airport when I returned. I think all the pilots up here try and get in the air when we have clear days in the winter. I got my fix again. KR/Corvair life is sweet.
