Vacuum Advance on 2000cc

Post by Gornal » Sat Apr 27, 2019 8:36 pm

Hi,

I have the vacuum pipe attached to the distributor and think it terminates on the top of the manifold but it has always had a cap on it. Is there somewhere else where the vacuum pipe connects to? Not sure if this actually needs to be on here as the distributor has been upgraded (electronics inside)?

Any support would be great, thanks

the vacuum advance should connect to a small brass vacuum nipple on the bottom of the carb closest to the firewall, near the throttle plate. Do not connect it to the manifold, that is way too much vacuum and will over-advance the car, all the time.

Thanks a lot, very helpful. Any pics what this may look like? I can’t seem to find it but it is hard to see under. I take it this is the only one under the carb closest to the firewall so should feel different to the other carb?

It may be different on the 2000 - but here it is on the 1600 SU.

David, Your vacuum line from distributor should terminate at the nipple just below your fuel line on front carb. I see from your pic that nothing is there. That is for U20.

Found it! It was actually on the carb closest to the radiator! Must be a modified set-up I am assuming. I found some old pics I had prior to the restoration and saw it there.

thanks for the info

I think that is standard on the 2000 - that it is on the front carb, that's why I specified that the drawing above was from the 1600. I sort of knew that, but since I wasn't positive, I posted as I did. Glad you found it!
