Narrative:

Engine #1 fire on taxi in flg. Sequence of events as I recall them. Started #2 engine. Started #1 engine, hung start, shut down #1 engine, fuel cock, boost pumps, alternator and generator. Taxied on #2 engine to perform xbleed start on #1 engine for higher manifold pressure. About 20 seconds into taxi, tower notified us of smoke from #1 engine. I continued the taxi while motoring #1 engine to clear fuel. 10-20 seconds later tower reported flames -- no cockpit warning of fire. Immediately after tower's warning, another voice on radio confirmed seeing fire. I instructed copilot to open cabin door and verify fire, #1 engine showing high egt, but no fire warning. Copilot confirmed seeing fire. I discharged bottle #1 and instructed copilot to prepare passenger for evacuate/evacuation. Master warning and fire bell indicating fire in #1 engine. I released bottle #2 and called for evacuate/evacuation. Copilot evacuate/evacuationed and secured passenger, I executed engine fire and shutdown checklist. At that time fire department, called by tower, shot agent into tailpipe of engine and along left side of fuselage. I evacuate/evacuationed. Passenger were escorted into main terminal and aircraft was towed by FBO clear of taxiway. At this time I am unaware of the cause of the engine fire, or how I could have prevented it.
