Hi all,
I have (I believe) a 1995 Metro A+ engine that would have originally been fuel injected, prefix 12A2DJ01. It's never been apart save for changing the diff ratio to 3.7 to suit an Aussie 13" Moke, and now runs twin SUs instead of SPi.

I'm not sure if this engine would have had a distributor from the factory, but since I've owned it, it's had an AUU1086 dizzy. The only reference to this I can find is an old post of Spider's on the Moke Forum, but I don't really know enough about dizzies to know what I'm looking at. He states:
 

"That model was fitted to the 1300 MG Metros for the German and Spanish(? TBC) Markets. It seems to be a 64DM4 with a lot of mechanical advance."

 
In order for this engine to run with a remotely acceptable amount of power, this dizzy has to be astronomically advanced to the point that the engine is difficult to start in cold weather. It does have a vac advance hose, but I can't tell that this makes a hell of a lot of difference if its removed. If the dizzy is retarded back from where it currently sits, it loses all guts going uphill and flutters and backfires under acceleration.
 
I'm all but convinced the dizzy is at fault but the only replacements I have on hand are for A series blocks and so naturally that won't work. To make matters worse, in the first few weeks of this engine being in the car, the coil died on the way to work and I had to source a replacement. I've been running with that replacement CC215 coil ever since, but this too may not be correct? From the same post referenced above,

Also, there is a particular coil you need to run with, Lucas Part No. GCL143.

 

So, what I'm asking is this: What dizzy and coil combination should this engine have? Is what I have correct? Do I have to buy something else or can I send this dizzy away to be mapped correctly to my cam? If so, what cam have I got assuming this engine is untouched as I believe it to be?

 

Thanks in advance - pun not intended!

Given the engine you have there mate, probably the most ideal distributor would be a Lucas 65D4 S/N 42535A, though there would be a few others that would also suit. I can check when I'm on the office tomorrow.

For the advance curve, it is best to check it as it may have been modified or defective. There is a couple of companies who advertise recurving/repairing them and there are many more companies who do it but don't advertise.

 

 

I can't see the specs for that coil - a common issue as nobody lists the specs. I usually check it by entering a vehicle's details that I know uses the coil type I want.

 

Two ways to verify the correct coil:

 

- check the resistance. around 0.9 to 1.5 ohm should be ok. Outside of this range will kill the coil or module.

- check the dwell. It will be quite low at idle - 10 to 20 degrees and go up as the RPM is increased. If you are seeing higher than say 40 at around idle, the coil is wrong or there's a poor connection.
