Another shade tree mechanic trick is to rotate the engine until the cylinder to be worked on has the exhaust valve open and hook a shop vac up to the tail pipe in the blow mode. This will give a constant stream of air coming thru the hole you are tapping. Watch out for metal shavings in the eyes!

Damn plugs always gall up at the most inoportune time. I had one do that 5 minutes before time to line up on the grid at a race at the old Riverside track. I made the race. Lots of panic fixing the threads. This was in a kart, BTW. I wish I drove Riverside in a car, but never did.
