Thank you to all who replied. The pictures were, of course, the most helpful. It seems, from some comments that I recieved, that this is shown in the Bible - errrr, Bentley. WHERE? I have been through that thing, cover-to-cover, and didn't find what I was looking for! My Bentley has been with me through 4 vans, and two engine rebuilds, and that still p*sses me off! I have to thrash around and try to remember every time I am trying to set the timing, or checking valves... I have lost my hand drawing several times.

  Maybe this time I should draw it IN the book...  ...nah - that's too good an idea....LOL  ;-)
