Might I suggest that to deal with the trash left behind in the cylinder, that you drop by Home Depot, buy a few feet of clear flexible tubing (small enough to go into the spark plug hole).
Attach one end to you vacuum with tape, insert into the hole and then turn it around in the hole. The flexible tube has a natural bend to it.
Good luck and this reader has read this thread with great concern. Another fine reason to swap plugs every 30 and check gap every 15. Plus antiseeze of course.
GLAD IT WORKED OUT!!! You get the "Damn your lucky" award nomination this week.
