Here's something that might save you some trouble later on, if you have an
air compressor handy: When you first loosen the spark plugs, before you
back them out, use your jet-tip on the compressor to blow out the recess
in the head where the plug is mounted. Then, when you install the com-
pression tester, and the plug again, there's less of a chance for any loose
bits of grime, rust, sand, etc. to be knocked down into the cylinder, where
they could cause trouble as bits of abrasive junk.
