Rocker / Valve assembly
Having purchased a digital copy of the original engine’s service manual:
Vendor : Weak Force Press (Huntsville, Alabama, USA)
Photos and Drawings
This manual provided a wealth of information on the major components and a crucial cross sectional view of the rocker / valve gear.
Components are rotated in this cross-sectional view for drawing convenience.
Using a combination of photos and cross sectional information, I have been able to rebuild the piston assembly, making it more representative of the original engine.
