FBD:
You sure know how to bring a conversation to a screeching halt. I would have thought as a "moderator" that you would strive to encourage input, not stop it. Why don't you find other people's experiences real? It may never have happened to you, but that doesn't mean it hasn't happened to someone else.

Now, I'm no engineer, but it seems logical to me that the glow igniter is attached to the motor to create a spark and start the engine. Once the motor is warmed up, we pull the glow igniter OFF the motor, yet it still runs, I guess because there is enough heat in the engine to keep the glow plug igniting. No one leaves the igniter on the engine when they fly. So, if the engine is still hot enough from a previous flight, there's combustible vapors in the carb and compression in the motor rotation, it seems perfectly reasonable that the motor could start without the ignitor in place. Doesn't that make sense to you?
