Both the nulite and Coleman are running but I have some questions. First how many pumps at first to get it going? The pump I have is around 4 inches long. The nulite just has a ring for the globe. Does the globe just sit on it?
You have an iron pump, rather than a lamp pump. I'd count about 40 strokes, and then judge it from the burn intensity. It's all part and parcel with how much fuel you have in the fount. Not sure on the Nulite. Photos always help
