In AU they call the distributor "dizzy". Yes you can use the A12 distributor in the A14 or A15 engine. You might have to file a little bit on the base plate (mounting plate) to get it to
mount right. The electronic distributor should work, all you have to do is hook one wire up to the positive of the coil, and the other to the negative.

I've checked my compression in my engine, and according to that chart you put up, I would have about 8.5:1 compression in my A15. I think that's a little too low since I'm trying to get
more performance out of my engine, but it works until I have to pull my head.

I've pulled my spark plugs since my 1200 has been acting up, and I also have found some oil on them. The plugs themselves are a nice brown color, so it's got a good burn though. Does
this mean my head gasket may also be the problem?
