I understand the last thing you want is to feel the wrath of the spark of one of these units sooooooooo.............Once fired up is there any risk of getting a good zap when turning the distributor to adjust the timing while it is running?
You should be fine as long as the wires aren't arcing anywhere, and everythings set up properly. But I will tell you that it does give you a nice jolt, it's happened to me once before lol.
