With all the Turbo City engine components on, it was time to try our Firepower ignition kit we had ordered from 4WD Hardware. We started with the Screamin' Demon coil that is a direct factory replacement featuring brass terminals, which allows us to gap our spark plugs at a recommended 0.065 inch for a bigger spark and more complete burn of the fuel mixture. The coil looked easy enough to get to, but we soon found easy-looking and easy-doing were not the same things. Though it only has two bolts holding it in place, one of the bolts was very tricky to get a tool onto.
