Aircraft; Human Factors; Procedure
Newly installed non-pressure compensating fuel pumps. Not used to leaning or enriching in-flight. On descent; [I] had some engine roughness. Leaning the mixture helped. Despite checklist usage; left the mixtures lean for landing. Upon turning off the runway onto a taxiway; the right engine quit. I stopped and tried to restart as a hot start from memory. With the fuel pump on; mixture rich; and starter turning; the right engine caught fire. Several people on the ground; and the test engineer in the right seat saw it and notified me. Again; by memory and not in-line with normal POH (Pilot's Operating Handbook) procedure I put the mixture at idle cutoff without continuing to crank the engine with the starter. I also did not first move the fuel selector to OFF. The fire went out almost immediately after pulling the mixture to idle cutoff and we exited the airplane without further incident.Lessons learned...practice memory items. I did not act in accordance with the POH for the condition and we were lucky the fire went out and didn't cause any damage. Think about the procedure before you do it. Leaning the mixture on descent hadn't been needed previously in this aircraft; but with the new pumps; it was. It was something that I did not remedy with the landing checklist since the previous fuel pumps did not need leaning or enriching below 8;000 FT. So when the checklist called for 'Mixtures - Rich' I just by rote; completed that item without checking. That probably caused the engine to quit on the taxi roll.
BE58 pilot reported that after landing an engine shutdown; and while attempting to restart; the engine caught fire.
