Re: Problems with new kit...
If you have a slant head, you can remove the head and turn it around, so the plug slants the other way. If that will give you decent clearance, do it, torquing the head nuts to 120 inch-lbs.
I'm not sure I understand what got ripped off of what, though. The only thing I can think is the wire end cap that goes on the plug got removed from the wire. If that was put back on badly, your spark will be weak.
Could also be a bum plug, if it's still the kit one. NGK B6HS or one of the iridium equivalents is what you'll want.
