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.
