Ok i got a battery operated glow igniter which uses a C-type battery and it turns out that the battery lasted only for around 5 uses. It does heat up the glow plug but it's not all the bright orange.. On the other hand i think the glow plug is messed up.

The meter on a new battery on the glow igniter goes between 2 and 6 when connected. After 5 uses it only stays at 2 and I think that's make starting the engine also not soo easy.
