The Churchill (British Ford) jigs main purpose is to set the dwell on the two sets of points (as are the jigs for the other types of dizzys) They also pre-set the timing but this can be altered.

Superb idea Lynn... I will do exactly that ... I didn't realise such a thing as distributor graph existed. Thanks for the helpful tip !

By the way .... Is it possible for an inlet and exhaust valve to both be stuck closed on the same cylinder? Cylinder number 2 is missing on my engine and I've conducted a pressure test and noted 95psi across all 8 cylinders. I was expecting a low or zero psi on that cylinder ? But it's ok for pressure .. Spark is strong ... I've swapped spark plugs around ... and I'm not sure what do do next
