N.B.
THE MEASURE «A» TO TAKE IS A PISTON PROTRUSION VALUE THAT INDICATES HOW MUCH THE PLANE
FORMED BY THE PISTON TOP PROTRUDES FROM THE PLANE FORMED BY THE TOP OF THE CYLINDER.
THE MORE THE PISTON PROTRUDES FROM THE CYLINDER, THE MORE THE BASE GASKET TO APPLY (TO
RECOVER THE COMPRESSION RATIO) AND VICE VERSA.
