I'm still working on my first build and having trouble getting it to start. I noticed that in order for my spark plug's terminal to fit into the CDI slot, I have to unscrew/remove the terminal nut on the end. Is this okay? Will the plug still work? I have another older CDI that doesn't require this. I presumed the older CDI still worked, and that maybe the reason my bike won't start is something else, but now I'm not so sure.
