George:
You were correct in your assumption; the kero plug startup valve solenoid was partially or fully stuck open after startup and was feeding excess fuel into the turbine. Once started and in Stabilize mode, I turned off the manual valve in the kero startup line and the hot spot on the nozzle never showed up (see short video). Restarted multiple times with same procedure and no hot spot. Also compared data from runs from 10 years ago to this latest run and had very similar numbers (except my fuel pump and / or filter may need attention / replacement).
Before you “fixed” it George, I was going to drop the Titan off to you when we went to visit my wife’s relatives in VA Beach for Christmas. But the COVID thing is keeping us in Ohio this year….
Thanks again, George. Hopefully I will see you at one of the jet rallies next year. Stay well……
David: I hear what you are saying and may still have George "service" it in the future....
