Crying comes to mind!

First try to get a thread chaser for the plug hole. Grease the threads up big time and try to ease the chaser in. The grease should catch most of the cuttings. If the chaser works, use a small light and check the chamber for any junk. Get all of it out.

If you aren't comfortable with the chaser, pull the head and repair it with a helicoil or similar repair.

From what you say here, it sounds like it is cross threaded and that it didn't go all the way in. If that is the case do as Skip suggests with the thread chaser and see what you get, as a last resort you can pull the head to repair the damaged threads. You may also consider the use of a timesert which is stronger than a helicoil in this situation to repair the damage.. http://www.timesert.com/

You could atempt this without disassembly, but great care must be taken to remove any shavings from the cylinder before starting the motor.

When reinstalling the plugs, don't forget to use antiseize on the threads.

Cross threading most likely. People should always install sparkplugs by hand until the plug seats on the face of the plug hole. Anyway, if you really jacked down on the cross threaded plug with a wrench, you need to pull that head for cylinder cleanup and thread repair. Dont even attempt to leave it on. A good number of metal shavings have already entered the chamber most likely.

Yeah, timesert! I always forget the name. Much better than the helicoil kit.
