Careful!
You may be drowning the glow plug with fuel, and by turning up the voltage you are burning up the fuel that is pooling.
In effect, you are compensating for an improper starting proceedure by turning up the voltage.
Check your glow plug by directly connecting it to the voltage source while it is out of the engine. Does it glow at 1.2 volts?
Glow plugs are supposed to be used with LESS than 1.5 volts... they were designed with 1.2 volts in mind.
Instead, try fueling in such a matter that no fuel is pushed into the carb. Then do NO priming.
Attach the ignitor, and keep turning the engine over with the electric starter until it starts up.

It could be you are using too high of a voltage, or it could be that the engine is new, or the high end is a bit too lean.
On a new engine small particles slough off as the engine wears in, and coat or affix to the glow element. This greatly reduces it's lifespan.
On some new engines I'll get a few flights on the engine, then the glow plug will burn out, or idle will be adversely affected.
Replacing the glow plug cures the idle problems, and typically after the first or second plug, subsequent plugs seems to last forever.
