I slowed down to a stop, and once stopped I looked in shift 3 to see if I had forgotten to take pitot cover off, but it was off. Next thing I checked was pitot heat, but i had turned that on when I finished runup. ( there was my mistake) By the time I started takeoff roll, the pitot was plugged with ice. I waited a few minutes, and started takeoff again ( plenty of runway left) I saw airspeed start climbing, so I figured everything was back to normal. I got up to about 75 knots, and the aircraft rotated by itself ( I must have been much faster than 75 knots for this to happen cause my normal takeoff trim was set correctly) . I started flying, adjusted climb power, and airspeed still read 75 knots and would go no higher. Seeing that I would have been close to a stall at this point, but I was climbing, I decided I still had a partial blockage of pitot, so I flew using the AH at about a 5 degree pitch up. After a long minute or so, the ice apparently cleared, and airspeed gradually went up to 120+ knots. Lesson learned, turn on pitot heat in these conditions right after engine start.
So now I am up to altitude, and cruising, and I checked my airspeed, and see it was around 120, and it should be closer to 140. I now realized that in the scramble to get the airspeed issue solved, I totally forgot to raise the landing gear. Rule two, when something goes wrong, go back to the checklist and make sure you have done everything, like raising the landing gear.
