Do all 2litre CU engines have vaccume advance?

Post by The_blue »

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?

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:

Anyone have the '009' centrifugal advance figures? then I can plot that too..

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

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?
