I'm new at this and need help with several questions. I have a Hangar 9 alpha trainer.

1. I have a hot-shot 2 Glo-starter. do I lock on the glow plug until I get the engine started?

2. I have a torqmaster 12 volt starter. when I tried to start the engine the propeller nut spun off. The engine is suppost to start counter clock wise and I had the starter turning counter clock wise. How can I keep the propeller nut from coming off?
