THE PILOT REPORTEDLY DID AN UNUSUAL AMOUNT OF ENGINE RUN-UP BEFORE PULLING ONTO THE RUNWAY. HE THEN PERFORMED ANOTHER RUN-UP BEFORE DEPARTING. THIS IS EVIDENCE THAT HE WAS AWARE OF A PROBLEM WITH HIS AIRCRAFT. THE ENGINE(S) WERE POPPING AND PUFFING BLACK SMOKE DURING THE GROUND RUN. YET, THE TAKEOFF WAS CONTINUED. THE POPPING AND SMOKE PUFFING CONTINUED AFTER LIFTOFF. A NOTICEABLE LOSS OF AIRSPEED OCCURRED DURING THE CLIMBOUT.
