your glow plug is good if it glows its good.. it might be weak.

did you leave the glo starter on it while you where starting it up?? i leave mine on for about 10 secs after it starts just to make sure it will stay running..

but make sure you charge your glo starter four about 10-12 hours for the first time, otherwise it wont work as good the first time you use it.

any other ??? just ask we are all here to help!!!
