[Healeys] Pertronix Electronic Ingnition for BJ8 with TR6 Distributor Cap

[Bob Spidell]

Side note:  I recently bought a second Pertronix as a spare.  My original Ignitor--fitted many years ago--was part# 
LU162P12, the newer one is LU162P12A.  I fit both units with spade connectors to allow easi(er) and quick(er) 
installation, and when doing so noticed the later unit had a different baseplate configuration.  It appears the 
Pertronix 'pickup' sits 'earlier' in the firing sequence; e.g. if the old unit fit at 6 o'clock in the distributor, the 
new one fits at 8 o'clock (the distrbutor cam turns counterclockwise).  I expect if I have to fit the spare in the field 
my timing will be grossly advanced.  I figured I could change the timing to get a decent idle, then drive carefully to 
see if there's any knock and retard from there (or advance until I get knock then retard).  I don't want to carry my 
advance meter at all times, but if necessary I'd buy one--most decent parts houses and Sears--should have them, and set 
the timing correctly.
