Smoke in the Turbine duct P-80
last Saturday I flew my avonds F-16 twice, never happen to me before, being flying the P-80 for two years now, after shutting down by the normal procedure there was smoke in the engine duct on the two filths, mostly sure an unburned fuel, can be that the solenoid valve is went bad? what can be the cause?
