ok, so you're just removing the spark plug lead - no need to remove the
head for that. worst case, get yourself something like a hole saw, but
if you use a long thin screwdriver, you should be able to pry the stuff
away from the tube wall. after that, long nose pliers are your friend.
before you remove the plug, use compressed air [or a pc duster can] to
blow the loose debris out after you've pulled the big chunks out.
