well, its a new cooker (cajun cooker i believe)that i bought back in the spring. it doesnt have any dirt dobber nest in it. it has a 10lb regulator on it and a valve on the end of the regulator. when i put my lighter up to the burner and turn the valve it lights and the flame will not get any larger no matter what position the valve is in. but, when i turn the valve open before lighting say about halfway or better then put the lighter down there it will light and is fine. i can adjust it up and down, kinda weird. guess i will just continue to light it at a higher level.
