Geee!! the back end of that engine looks bad lol.. from the looks of the turbine wheel and the cone..there is now some serious rear (bearing cooking) worse it's Kero start. That means if there was repeated hot start eventually the rear bearing is going to bake. My friend have the Propane start version so it less heat on start up.. I wouldnt start it again, time to send it in.

P.S I would send it with all supporting equipment so Barry can find tune it ...That's a tough engine lol.

Good luck
