Hi, I am totally new to this. I bought a nice Coleman Camper stove several years ago. Only used it once or twice. I went out to my storage shed to see what it needed 'just in case". It has been stolen ( I know who is was, but have no proof). With money being very tight now, I found a used one with three burners at a local thrift store. But it needs work and I don't know where to start. Sorry to sound like a girl (that's what I am, although an old one, ). Any help will be appreciated.
