My guess is your not priming it correctly.

Now if your glow sticks charged, the plug is fine and you've primed the engine then is should start.

Now you've admitted to being a noob and I hope this doesn't in sult but here is a check list for you.

1 Take out glow plug and test it on the end of the glow sick. It should glow orange (if it's wet it will hiss)

2 With the plug out block the exhaust hole and pull the cord a few times till a mist of fuel comes from the plug hole.

3 Refit the plug loosely apply the glow start and try to start the engine.

4 If it fires up the remove the glow stick and tighten the plug. (Carfull here as the plug may pop out if your not quick enough, but dont panic and rush and it may cause glitching of the servos as the metal objects touch.

5 If it doesn't fire, Then you either have a worn out piston or a tuning issue. So does it make a poping sound when you turn the engine over or does it lock up and get so tight you cant pull the string?

Let us know and then that will guide us down the right path.
