So that valve - advance , or lead , will be the first requirement in remodelling the
engine of Fig . 2 . In these reference plates we are using a " return crank "
eccentric , which shows the exact point at which the valve gear receives its initial

Shortening the throw of the eccentric by changing it to a point nearer the hub
centre would take away the increase of travel that was developed in securing the
advance of the valve , —would it not ? Certainly ; that would be a good way out of
