The vacuum advance/retard units are not easy to find. I searched for years to
find a working one without any luck. The retard side was used to decrease
idle speed to reduce emissions, it's not needed. The important thing is to
time the ignition as though the retard isn't there (actually, it isn't).
Instead of timing my GT6 MKI at 4 degrees ATDC (recommended setting with the
retard), it's timed at 8 degrees BTDC.

I recently purchased a '72 GT6 (drove it home from Ozark, MO Saturday) and
need some advice/info. The car has what seems to be a non stock coil (with
external ballast) and a bad vacuum retard unit. Any idea which coil set up
is
stock and where I can find a retard unit? Other than that it is pretty much
all original. Any help would be appreciated and there will be more questions
to follow!!!
TIA
