Measure cylinder walls for taper, out-of-round or excessive ridge at top of ring travel.
This should be done with a dial indicator or inside micrometer. Carefully work gauge up
and down cylinder to determine taper and turn it to different points around cylinder wall
to determine out-of-round condition. If cylinders exceed specifications, boring and/or
honing will be necessary.
