I think Barry can say something about my problem.
Today for the first time I started my K-140 kerostart, it started with no problem, I leted stabilize on iddle and put it on full power, did this like 10 times, no problem, bu when I send the command to stop, the turbine run a little time and then locked, I saw that and give a little tap on the compressor and it started to run free like nothing happened and finished the cooldown sequence, there was no strange sounds, no vibration, nothing, I examinet the compressor and the turbine wheel and theres no sign at all that they rubbed the case, I have 2 K-80's and never saw this, the turbine is running free like nothing happened.

It's very strange, what do you think it happened? O well I was putting a big hoppe into this engine []


Thanks guys.
