PB-620- yesterday while blowing, motor began sputtering at times, would smooth out and sputter again. Upon checking the plug wire, I noticed it is attached to the actual spark plug by some type of coil thingy on one end. Only a small piece of metal actually penetrates the wire sheathing to make contact with the wire inside the boot. I've always been into automotive stuff and never seen a configuaration like this. Looks kind of cheesy. Anyone ever try and use automotive wire cut to length with normal connectors?
