Interesting, jaguar. I came across a camper web blog last night that said the same thing. Guy said he uses unleaded gas with a touch of fuel injector cleaner in it and that he cleans the "generator" with a .22 cal bore brush after soaking it in break cleaner. He also mentioned the fragile tip.

This is why the coleman stove is so appealing as a casting tool - many fuels can be burned in it. I also think I want an excuse to buy one.
Thanks for mentioning this.
