When I purge my nitrous I dont see a white cloud. the purge seloniod is clicking, but only compressed air is coming out. I dont think the bottle is empty. It's very cold out, could that have something to do with it?

N2O usually has sulfer mixed with it so that you would know if the bottle was leaking. It also keeps people from using it to get high. I guess it depends where you get your bottle filled though. Some places might not do it.
