Timing

[wild_willy]

I set TDC on my Nippy (9E head without direct access to the piston) using a thin piece of rod placed into the plug hole at an acute angle so it rested on top of the piston.TDC can then be found by feel and the mid point of the piston null judged quite accurately . I then filed a small notch on the edge of the fan pulley and made up a pointer in line with the notch (care would need to be taken if the pulley is ever removed to ensure TDC is again found and the pulley re aligned with the pointer). Timing can then be achieved easily using a timing light. If you have a read back style electronic timing light, total timing can be assessed as well.
