This is why I do my own work on the Midget but take my Mitsubishi to a shop
that has all the right equipment and technicians. They have access to
Mitchell On Demand and other tech help.
Maybe you could install a Lucas distributor and coil. Then you just have to
set the points.
Sorry I can't really help. Don't mean to sound like a smart a$$!

<< I have a 92 Saturn which has been running rough at cold startup and ping
under a fairly low load. It has a DIS ignition system, and I get no flashing
error codes when I short out the correct contacts. I checked the RPM's with
my Fluke meter: plugs 1 and 2 don't seem to have a spark according to the RPM
meter function (I don't get any RPM's at all); and on plugs 3 and 4 I get an
RPM reading. I should think I should get a reading on all 4 wires, right?? It
has two coils: coil one services 1 and 4, while coil 2 service 2 and 3.
I opened the Chilton's manual and they suggest testing the resistance
between the two posts of each coil: it should be around 30,000 ohms or so.
The first coil showed the 30,000 ohms, while the second one showed several
Mega-ohms. That suggest the Mega-ohms coil is bad. Problem with this is that
I was getting a spark on one of the wires leading from that coil.
Chilton's says a Mega-ohm coil should be replaced, but I went on as
Chilton's also suggests switching the interchangeable coils. I did this, and
the high Ohm coil was still high Ohm, and the low Ohm coil was still low.
This again suggests that the high Ohm coil needs to be replaced. Problem is
though, the same two wires still are dead and the same two wires show an RPM
reading.
This suggests that the problem is in the ignition control unit; two circuits
are bad and therefore the icu should be replaced. Problem is, I don't get any
error lights, and off of the "bad" coil I am still receiving a spark. >>
