Adding a vent to the lid will add draft.
This in turn will cause accelerated combustion in the pit, raising temps.
This mod avoids the neccessity of utilizing other methods, such as hooking the door upside-down, and propping open.
Thanks for the great advice guys. I just ordered the vent kit, I cook alot of chickens so this vent will come in handy.
