Alright, I managed to get some pictures of the little black box I was trying to describe. Here the setup--the black box (which is actually just something inside of some soft black rubber covering) has many wires coming in and out. One set of wires comes in from the switch, and go out to the magneto. The other set comes in from this round charger looking jack (located just below the switch on the fuse side), and it goes to a little copper thing that sits right next to the magneto. I have a picture of it as well. What the heck is all of this stuff? I figure it's a kill switch, but what's with the box? Is it some sorf of RF filter, or what? It doesn't appear have any kind of battery.
sorry about the quality of pics. My camera is about as worthless as **** on a boar hog...

The pics:
Help is greatly appreciated..

BTW, the engine has one ring, does that make it a 35 CC? Where can I find info about US engines?
