I received a Coleman 530 I ordered in the mail recently. I've wanted one for a while, but I waited for a decent example that was made in Canada, complete, and was a decent price to show up. The one I bought is a 2 '47. What almost 50 years of using Coleman stoves and lanterns exclusively with white gas didn't prepare me for, though, was the STINK of a stove that was run for decades on gasoline. Holy moly! The thing is eye-watering! And the unbelievable amount of crud built up inside the thing, and the layer of stinky tar on the outside! The stove is in good shape, but the amount of work to de-stink it and clean all the guck out is incredible. Even the aluminum case/pot set reeks of gasoline. I've resorted to soaking some of external parts in a bath of TSP to break up the smelly tar. I don't even think I will try to fire it up without replacing the generator first. The brass screen inside is so caked with goo that I can't pull it out, even after a nice soak in carb cleaner. Any good advice on removing ancient gasoline crud?
