I hope you didn't move the low speed needle too much?
Tune with the glow attached for now.
At full throttle pinch the fuel line going to the carb (be carefull of the prop) if it increases rpms before dying it is rich if it just dies it is lean. Find the point where you are right in the middle and turn the high speed needle about 1/4 turn CCW to run just slightly rich.
Repeat the proccess for idle with the low speed needle, turn the engine off when adjusting the low speed needle.
You should now be able to run without the glow ignitor, adjust again.
This is all assuming you have the plumbing hooked up correctly and the glow plug is good.
A better bet is to find an experienced pilot at a local club to help you.
