I've just finished a trial re-fitting of the lumenition system and all is well.
Interestingly I also found that the static setting gave 3 or 4 degrees retarded at full advance when checked with a timing light.
I haven't accurately measured when full advance is reached, but it's in the range of 2000 to 2500 rpm, so ties in well with Hendred's 2200 rpm.
Within the limitations of accuracy of measurement, the timing at 0.3" btdc equated to 33 degrees measured on the alternator rotor, agreeing with the calculated value.
