Reynolds diagram No 3.

Scale ½ full size
This drawing should ideally be enlarged to full size and used as the datum to set up the engine when completed noting the angle of the wrist pin in relationship with the positions of crank and piston and crank as stated. Note also the attitudes of the inlet valve bell cranks and all other levers. If scaled up as described it can be the main reference to produce the governor parts, piston rod guides, and several other details.
