According to my Haynes 'Weber, Zenith-Stromberg, and SU' book, you take the
spark plug out and screw the tester into the cylinder (there is another type
that you hold over the hole--not recommended by the book). Then, you take
the HT lead that goes to the dizzy and ground against the engine. Finally,
you bump the starter a couple of times to read the pressure. It says if
there is a difference greater than 14 to 21 p.s.i. between the cylinders,
you need to work on the engine. It also gives a reading of what it should
not be below, but I can't remember (I'm doing this from memory--trying to be
like Frank--maybe in another 20 years).
