Dad has always taken care of the grilling. Well I'm not doing so hot so far. At least that I think of. So anyway, I pyramid the coals, good bit of lighter fluid(enough it flares up at me) and they don't stay lit for more then a few minutes. Bag says should be about 15 minutes before they die down and turn grey. So whats up? Is this normal and I should just walk away? I'm using kingsford coals and fluid. Its what my dad has always used so thats what I got.
