Sears Craftsman. Ignition wrenches is what you want to ask for.
Bruce is showing his age! They are no longer called "ignition wrenches" but are referred to as miniature or micro wrenches. They don't make ignitions where you need these any more!!

I still have mine from the the first set of Craftsmen tools that I bought when I was 18 years old, and the plastic envelope that they came in says "ignition wrenches.' I got another set with a tool set O bought about 20 years ago and those said miniature or something like that. Either way, they are handy. If you are looking for tools for working on needle valve spray bars and such, Jim Lee has some really neat socket wrenches in his offerings. Those, and some old fashioned nut drivers, which are 6 point, along with the ignition wrenches cover just about everything. OS and Saito usually give you some wrenches with their engines when purchased and you may find those at swap meets and such.
