Hello,
Does anyone know which way round the vacuum delay valve on the distributor should go? mine is green and white and i cant tell by sucking on it as it is hard to suck in either direction:( some pople on the internet say you dont need it but i have tried running without and the car drives rubish.
Thankyou for your help.

Use a timing light, the timing should advance as its revved.

I can't find this valve in any of the manuals.
Any more info ?

it sits in line of the pipe that comes of the vacuum advance. im not sure if it matters now though. thought it was a one way valve but ive tried it both ways round and it doesnt make a difference.

I'll be honest, mine hasn't got one, and I don't think it ever has? Have you got a photo of it? It sounds like the one way valve on the petrol tank....... And mine was like this it was supposed to be directional but I could blow through both ways

yer, il try get a picture. its a bit weird though as if i take it out completely the engine has no power at all when driving. strange as i know lots of people run without them.
