Such is my relative newness to this game I don't have a compression testing kit yet. But I like the concept of being able to diagnose a lot better myself.

But even trying to find a stockist of Mityvac is difficult here!! Does anyone know where I can get W123 workshop manuals on CD? I have tried eBay UK and US but there are none for this model.

As for the coil, it is only £28 (about $50) which in the great scheme of things is peanuts and at least I can eliminate it from my enquiries.
