The length «A» to be measured refers to the pistón protrusion. It indicates the amount by which the surface formed
by the pistón crown tops the surface formed by the upper parí of the cylinder. The more the pistón descends into the
cylinder, the less the base gasket to be applied (to recover the compression ratio) will be and vice versa.
N.B.
THE MEASUREMENT OF «A» MUST BE CARRIED WITH THE PISTÓN AT THE TDC, WITHOUT ANY GASKET
INSTALLED BETWEEN THE CRANKCASE AND THE CYLINDER, AND AFTER RESETTING THE COMPARATOR,
COMPLETE WITH SUPPORT, ON A RECTIFIED SURFACE.
