This is a factory Honda tool, and it's still available, though rare and expensive. It consists of a set of variously sized stainless steel wires housed in an aluminum case. It is designed to be used to poke a jet, and more importantly, to accurately size it. The wires don't have serrations on them, so despite appearing like an acetylene torch tip cleaner, it is not one. Honda inexplicably chose a seriously misleading package for this tool. And therein lies a "gotcha". Unfortunately, the aftermarket, in its usual asinine style, took the appearance and ran with it, and they offer torch tip cleaning file sets marketed as carburetor jet tools. They are not! Stay far away from them!
