0.3 flight time. Not much time today to do data collection, so went out and did 2 low passes and 1 full stop. Was in the afternoon this time, so quite a bit warmer and busier. 4 planes in the pattern. The guy in front of me on the 2nd pass had followed what I did and offered to stay down on his touch and go until I passed over. Saw 183 mph indicated at about 3100 rpm on the 2nd pass. The engine seems to be loosening up and capable of more rpm. Saw bubbles in the sight gauge on the 2nd pass in the pull out, and there was a bit of burbling on the engine at that point as well. I need to richen the mixture at the carb a little more.
