[DML] Re: Trigger/Stator air gap

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

The Delorean Workshop Manual does not have a good explanation for the
procedures involving the distributer. Maybe a Volvo or Renault Manual
is better? Anyway the pick-up coil is actually # 12. It is inductively
coupled to part # 17 and part # 8 interupts the coupling. The
dimension you adjust is the gap between the spikes on #8 and # 17.
Part # 8 is very easily bent so adjust it carefully. I would start by
making sure the spikes on #17 are all exactly equidistant from one of
the spikes on #8. Once I had all of #17 adjusted the same then I would
make each spike on #8 the right gap. You have to use a brass
(non-magnetic) feeler gauge or you will feel the magnetism, not the
gap. The spikes should not touch. Maybe something is loose inside the
distributer or the bushings are worn. If there is a lot of play in the
bushings do not try to set the gaps, you won't be able to. The best
advice is to completly disassemble the distributer and check
everything for wear. The play in the bushings should be minimal, like
a couple of thou max. The advance plate # 17 should be tight, ie, the
screws holding it to the housing should be holding it securely and it
should rotate smoothly for the vacuum advance. The picture on M:01:01
does not show the shaft and the mechanical advance. In any case you
should disassemble it too and clean and lubricate it. You may only
have to clean and spread the connections inside the plug on the wire
(#2) so as to get a better contact with the pick-up coil. Jiggling the
wire should not affect the motor if it is connected, clean, and tight.
That is also why there is a  plate and screw (#18), to hold it tight.
BTW you didn't have to remove the distributer to replace the wire
(#18), it can be done "in car", adjusting the gap is possible in car
but is MUCH easier "off car". You *should* use a timing light to reset
the timing when you reinstal the distributer. Making marks and trying
to put it back the way you found it assumes it was correctly timed
when you removed it (a BIG assumption!)
