Well airplane is an avistar
Prop is 11by5
The engine is fairly old it trained someone before me so I don’t know exactly how old it is
I’m thinking about putting a new plug on because the other is probably what went with the engine at first

And well as I probably did punch the throttle I will stop next flight

Da rock I didn’t understand post 5 so if you can reword it so a beginner without a lot of engine experience it will help
