Sounds like you flooded the engine and it Hydro-Locked.

Don't bother priming it if your using an elec starter... Also don't start it at full throtle your HAND is in front of it I can't believe someone gave you that bit of advice.

Watch the fuel line while using the starter to make sure fuel is getting to the carb (the hydro-lock means it most likely was but better safe then sorry)

If you can't see the fuel remove the line and the glow driver then spin the prop for a couple of seconds but watch your eyes fuel sould come out while the prop is spinning if not then you might not be pressurizing the system or have an air leak check all connections and the stopper
