Do all 2litre CU engines have vaccume advance?

Sorting the wiring on my new van and the vaccume hoses are all over the place. just noticed it hasn't got a vaccume advance on the side of the dist.
Did some come without? Does anyone have a good picture or diagram of what should be where?
Is this the wrong dist?

Yes, think they all do.
What you have there is an 009 dizzy, I think the somewhat (in)famous performance replacement with no vac/adv retard. I would suggest you source the correct setup, for emission and consumption reasons, as well as clean running.
I think opinions will vary but some seem to think that the 009 is 'the business' as it has this 'reputation', but I doubt for he CU engine - and yours isn't tuned and setup for it anyway I doubt.
This Wiki link may be helpful, CumbrianKeith is often the one to answer CU questions on Tech, and as you can see, he owns a particularly fine example:

Don't have the figures for a plot, but I observed only 7 deg full advance on mine.

It should look like this:

009 depending on how crap (later ones are poor quality copys.. it is will give 12-18 degrees of advance, from just off idle and finally all done by 3000.. the advance curve is all wrong for a type 4 engine.. bad bad news.. and even on a type 1 they need to be tweeked... and give flat spots..
Timing has to be done for 3000rpm+ and 32-34 degrees.... this will give a lot advance at idle... but thats bette than overheating the exhaust valves and seats....

Been to volks heven and got a new (to me) dizzy, control unit, vacume hoses and any wiring included or not fixed down
Those guys know how to charge though
You think this is the reason the plugs are black?

Possibly!
Sort the ignition out first clean the plugs and see... is that stuff 2nd hand then?
