I recently bought and installed this G38 on my Giant Big Stick. I'm wanting to install a kill switch, but would like some input on how to do this. This is my first magneto engine. Common sense tells me I can buy a switch at RadioShack and connect one side to the end of the red wire, then the other end to a bolt on the crank case or engine mount. Am I correct?? Anyone who has experience with this engine, please share a pic of your install, or just tell me if I'm ok to go with my idea. I was going to buy a toggle switch at RadioShack today if that's all it needs.. Thanks, guys.
