hey guys i have a problem, the dellorto manifold has no provision for dizzy vaccum and i have a vaccum dizzy so what can i do ? i cant see a vaccum outlet on the dellorto either

Err i think you can just discconnect the vacuum from the dizzy end and leave it. It does jack all if you don't have a SU I think...

Doc's car just has the vacuum disconnected too. I am assuming this is what I will do when I connect the dellorto

NOOOOOOOOOOOOOO!
Just leave it off. You will have WAY too much advance if you hook to the manifold.

Yeah most vacuum advance comes from the carb side of the butterfly, not the manifold side (although I think some pommy ones did for some peculiar reason that I can't remember). You're better off leaving it disconnected. Remember, it is an economy device. A dell'orto, on the other hand, is not (says he who ran out of petrol twice in two weeks and now carries 5L spare!)

My vac diaphragm was broken for years and I never noticed - I put a new one on and I don't think it did much!

Christoph's Weber has had a vac advance tapped into the carb body and it does sweet FA.

It takes 5 minutes to take the inlet manifold of macca, jeez your a rough bastard

G

thats why i said take it off
makka
give you ruff bastard
