I was at the airport this morning at 7am with heavy frost covering everything it looked like it had snowed. 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.
