I was thinking spark plugs before I got to the part where you mention you checked them. The loose plug may have been poorly grounded from being that loose.
Mine does run flawlessly, and it has even better reponse and low end power now that I've indexed my spark plugs which were both facing the outlets, adjusted all my valves to middle of range, and went back to stock airbox inlets from the louder oversize ones I had put in. It's so strong off idle now that I've considered putting the subthrottle plates back in, but I would do that only for when and if I ever sell it.
