Richard,
 I video tape my compression guage while cranking. This allows a slow motion
replay afterwards so compression can be plotted vs. stroke. Keep in mind the
first stroke will vary the most from cylinder to cylinder since the initial
position of the piston will vary. I haven't done this yet on our Westy.
Good luck solving your problem.
